The Store p520 Rectangle Hairclip: A Mid-Century British Classic
The code store p520 rectangle hairclip html shows up in auction listings, online archives, and collector forums. It points to a specific mid-century British hairclip — a rectangular barrette, typically 5 to 7 centimetres long, made from tortoiseshell-effect celluloid or polished metal. Unlike the ornate filigree clips of the 1920s or the sculptural enamel work of the 1960s, the p520 rectangle is restrained and geometric. It was designed to hold a French twist or a side-swept section of hair without calling attention to itself. Yet its clean lines and warm translucency have made it a favourite for modern vintage lovers who value understated elegance.
What Defines the Store p520 Rectangle Hairclip?
Product codes like p520 tell a story if you know how to read them. The p520 designation almost certainly comes from a British manufacturer active in the 1950s and early 1960s, when plastic innovation was at its peak. The 'p' likely stands for 'pattern' or 'product', while the number indicates a specific mould and finish. The rectangle shape — straight edges with slightly rounded corners — was a common silhouette for everyday clips, prized for its even grip without snagging.
Authentic examples of the p520 clip are usually made from one of three materials:
- Celluloid tortoiseshell – a lightweight, warm-toned plastic that mimics the amber and brown mottling of natural tortoiseshell. It was cheap to produce and could be moulded into thin, flexible forms.
- Bakelite – a harder, denser resin that produces a distinctive 'click' when tapped. Bakelite clips are heavier and often have a deeper, richer colour, sometimes with a marbled effect. They are less common in the p520 code, but occasional examples surface.
- Silver-toned or brass metal – some p520 clips were made from stamped metal with a spring mechanism. These are rarer and tend to be narrower, used for fine hair or as accent pieces.
The p520 rectangle hairclip is not one-size-fits-all. Its dimensions — typically 6 cm × 1.5 cm — make it ideal for medium to thick hair, though it can work on finer hair with a little teasing or texturising spray. The clip's interior has a small metal spring that provides gentle tension, holding the hair securely without pulling.
Materials and Techniques: The Art of Mid-Century Plastic Craft
Understanding the p520 clip means appreciating the materials that went into it. Celluloid, first developed in the 1860s, became the darling of the hair accessory industry in the early 20th century. It could imitate ivory, tortoiseshell, or mother-of-pearl at a fraction of the cost. By the 1950s, British factories had perfected layering colours — sheets of celluloid in different shades were pressed together, then cut and heated to create the characteristic mottled effect.
Bakelite, a formaldehyde-based resin, offered a different aesthetic. It was harder, more durable, and could be carved or polished to a high gloss. The p520 clips that survive in Bakelite are often dark brown or black, with a subtle sheen that develops a patina over decades. Collectors prize these for their warmth and heft.
Metal versions of the p520 rectangle clip were usually made from brass or nickel silver, then plated with silver or gold. These were often produced by small manufacturers in Birmingham's Jewellery Quarter, where skilled artisans stamped and assembled the components by hand. The spring mechanism inside a metal p520 clip is a delicate piece of engineering — a coiled wire that sits inside a hollow channel, providing even pressure across the entire length of the clip.

Styling the p520 Rectangle Hairclip with a Modern Wardrobe
The beauty of the p520 lies in its versatility. Because it is small and sleek, it can be incorporated into almost any hairstyle without overwhelming the look. Here are a few ways to wear it today:
- Low ponytail accent – Secure your ponytail with a clear elastic, then slide the p520 clip horizontally over the band. It adds a vintage touch without the bulk of a scrunchie.
- Side-swept French twist – Twist your hair from the nape of your neck upward, tuck the ends, and pin the clip vertically along the twist. The rectangle shape holds the twist firmly.
- Half-up, half-down – Gather the top section of your hair, twist it back, and secure it with the clip placed horizontally. Leave the rest loose for a soft, everyday look.
- As a hair brooch – For formal occasions, slide the clip into a chignon or a sleek bun, letting the tortoiseshell pattern catch the light.
The p520 clip pairs beautifully with fabrics like wool, tweed, and cashmere, as well as with silk blouses and tailored jackets. Its warm tones complement autumnal colours — rust, mustard, olive — and add a subtle contrast to black or navy.
Bereavement and Care: Keeping Your p520 Clip in Prime Condition
Vintage hair accessories, especially those made from celluloid or Bakelite, need gentle handling. Celluloid is particularly sensitive to heat and humidity. Never leave a celluloid clip in direct sunlight, in a hot car, or near a radiator. The material can warp, discolour, or even become brittle. Bakelite, though more robust, can develop a white haze from contact with oils or alcohol. To clean it, use a soft, dry cloth and avoid any chemical cleaners.
For metal p520 clips, check the spring mechanism regularly. If the clip feels loose or does not snap shut firmly, it may need a gentle adjustment. Use a pair of pliers to bend the metal prongs inward slightly, but work slowly — metal from the 1950s can be brittle after decades of stress.
When storing your clip, wrap it in acid-free tissue paper or place it in a soft pouch. Avoid stacking multiple clips together, as they can scratch each other. A dedicated jewellery box with separate compartments is ideal.
Identifying Authentic p520 Clips: What to Look For
Because the p520 code is often used informally in online marketplaces, it helps to know how to distinguish a genuine vintage clip from a modern reproduction. Original mid-century clips have a few telltale signs:
- Mould lines – On celluloid or Bakelite clips, you can often see a faint seam where the two halves of the mould met. Modern clips are usually injection-moulded with a smoother finish.
- Spring mechanism – Vintage clips have a visible metal spring that runs along the inside of the clip. The spring is usually made of steel or brass and may show slight patina. Modern clips often use a simpler plastic spring or no spring at all.
- Smell – Bakelite, when rubbed vigorously, emits a distinctive scent of formaldehyde. Celluloid may smell like camphor. Modern plastics do not have these odours.
- Weight – Vintage clips, especially those made of Bakelite or metal, have a noticeable heft. A modern reproduction made of thin acrylic will feel significantly lighter.
If you come across a clip marked with the p520 code in a charity shop or a vintage fair, examine the material carefully. The code itself may be stamped on the underside of the clip, often in tiny letters. Some manufacturers used a paper label that has long since worn away, so the absence of a stamp does not rule out authenticity.
Why the Rectangle Shape Endures
The rectangle has always been a foundational shape in design — it is stable, balanced, and easy to produce. But in the context of a hairclip, the rectangle offers something more: it distributes pressure evenly across the hair, reducing the risk of breakage. Unlike a curved claw clip, which pinches at a single point, a rectangle clip holds the hair in a gentle, parallel grip. This makes it an excellent choice for daily wear, especially for those with fine or fragile hair.
The p520 rectangle hairclip is a peak of mid-century British manufacturing: affordable, functional, and good-looking. That combination is rare in today's fast-fashion market. By choosing to wear a vintage p520 clip, you are adding a piece of history to your wardrobe and supporting a more sustainable approach to fashion. Each clip carries with it the story of a factory worker, a designer, and a previous owner who wore it to a dance, a job interview, or a quiet afternoon in the garden.
