The Store P501 Ric Rac Tortoiseshell Hairclip: A Collector’s Guide

The first time I held a Store P501 Ric Rac Tortoiseshell Hairclip, I was struck by its weight. Not heavy, but substantial—a reassuring heft that speaks of quality cellulose acetate, not flimsy plastic. The scalloped, zigzag edge, known in the trade as 'ric rac,' catches the light in a way that feels both playful and refined. For collectors of vintage British hair accessories, this piece occupies a special place: it bridges the post-war austerity of the 1940s with the exuberant textures of the 1950s, yet remains remarkably wearable today.

What Exactly Is the Store P501?

The 'P501' is a catalogue reference—probably from a mid-century British manufacturer or a department store’s own inventory system. 'Ric rac' describes the undulating, wave-like edge of the clip, a design element borrowed from ribbon trims that became wildly popular in dressmaking during the 1950s. The tortoiseshell pattern, achieved through layers of amber, brown, and sometimes a hint of dark red, mimics the natural shell of the hawksbill turtle but uses synthetic materials. This clip is a classic spring-loaded barrette, typically measuring about 7–8 cm in length, with a metal hinge and a firm snap closure.

Materials and Craftsmanship

The body is made from cellulose acetate, a plant-based plastic derived from cotton or wood pulp. Unlike modern injection-moulded plastics, acetate was often hand-polished and layered, giving each piece subtle variations in colour and depth.

The ric rac edge is not moulded but cut and filed individually, then buffed to a smooth finish. The metal spring mechanism is usually nickel-plated brass, designed to hold firmly without pulling hair. On well-preserved examples, you can still see the tiny screw that secures the hinge—a mark of repairability that modern glued clips lack.

The Ric Rac Silhouette: A Design Icon

The ric rac or scalloped edge was everywhere in mid-century Britain. It appeared on aprons, collars, and of course, hair accessories. The Store P501 takes this familiar shape and elevates it through material. The tortoiseshell pattern gives the clip a warm, organic feel that complements both dark and light hair. Unlike the stark black or clear clips of the 1960s, the tortoiseshell ric rac clip offers a softer, more textured look—ideal for the woman who wanted a polished appearance without appearing too severe.

Why Tortoiseshell Patterns Endure

Natural tortoiseshell was banned in the 1970s under CITES regulations, but the visual appeal of its warm, mottled browns never faded. Cellulose acetate versions, like the P501, became collectible precisely because they capture that aesthetic without harming endangered species. The pattern is not printed on the surface—it runs through the entire thickness of the material, so even if the clip is scratched or lightly worn, the colour remains consistent. This depth is one reason vintage acetate pieces age so gracefully.

How to Wear the P501 Today

The beauty of the ric rac tortoiseshell clip lies in its versatility. Here are three ways to incorporate it into a modern wardrobe:

• Half-up, half-down: Secure a section of hair at the crown. The clip’s width provides enough grip for medium-thick hair. Let the ric rac edge peek out—it adds a subtle, sculptural detail.
• Side sweep: Gather hair to one side and clip diagonally near the ear. This works beautifully with a chunky knit or a tailored blazer, bridging casual and smart.
• French twist accent: Use the P501 to pin the top fold of a low chignon or twist. The tortoiseshell pattern blends with brown and auburn hair while the scalloped edge creates a decorative border.

Pairing with Other Vintage Finds

If you own other tortoiseshell pieces—like the Store P23 Sergio's Platform Brogues or a structured handbag—the P501 will tie the look together without being matchy-matchy. For a more playful contrast, try it alongside a pastel scarf or a crisp white blouse. The clip’s brown tones also harmonise with denim, camel coats, and olive green, making it a year-round staple.

Authenticity and Condition: What to Look For

When hunting for a genuine Store P501, pay attention to these details:

• Weight and feel: Genuine cellulose acetate is heavier than modern acrylic. It should feel solid, not hollow.
• Pattern depth: Look at the edge of the clip. If the tortoiseshell pattern is visible on the cut side, the colour runs through the material. Surface-only printing is a red flag.
• Hinge condition: Open and close the clip several times. The spring should be firm but not stiff. A loose hinge can often be tightened by a jeweller, but a broken spring is difficult to replace.
• Surface patina: Minor scratches are normal and add character. Avoid clips with deep gouges or cracks near the hinge, as these can worsen with use.

Common Misconceptions

Some sellers will tell you any tortoiseshell clip with a scalloped edge is a 'P501.' In reality, the catalogue number refers to a specific size and hinge design. Authentic P501s have a narrow, flat profile—about 3 mm thick—and the ric rac edge has exactly seven scallops along the top curve. Clips with more or fewer scallops, or a domed profile, are likely from a different series. That said, many of these variants are equally beautiful and collectible in their own right.

Caring for Your Ric Rac Tortoiseshell Clip

Cellulose acetate doesn't like heat or moisture. To keep your P501 in excellent condition:

• Store it away from direct sunlight, which can cause the amber tones to fade unevenly.
• Wipe it gently with a soft, dry cloth after each wear. Avoid alcohol-based cleaners; they can dull the surface.
• If the clip becomes cloudy or develops a white bloom (a sign of moisture absorption), place it in a sealed container with a silica gel packet for a few days. Do not apply oils or waxes.
• Keep the hinge dry. If it starts to stick, a tiny drop of sewing machine oil on the pivot point—applied with a toothpick—can restore smooth movement.

Repairing Minor Damage

Small scratches can be buffed out with a microfiber cloth and a dab of automotive-grade plastic polish. Work in gentle circles, then wipe clean. For deeper scratches, a jeweller experienced with vintage plastics can sand and re-polish the surface, but this is rarely necessary for a clip that will be worn, not displayed under glass.

The P501 in the Context of British Vintage Hair Accessories

The Store P501 sits alongside other mid-century classics like the P188 Disco Diamante Hair Clip and the simpler shell-shaped barrettes of the 1950s. While the Disco Diamante clip sparkles with rhinestones for evening wear, the P501 is a daytime workhorse—elegant enough for the office, practical enough for a walk in the park. Its ric rac edge connects it to the broader craft tradition of decorative trims that flourished in British home sewing and millinery. Owning one is like holding a small piece of that textile history in your hand.

Where to Find and How to Choose

Vintage fairs in London, Brighton, and Bath occasionally yield P501s, often mixed in with boxes of miscellaneous hair clips. Online marketplaces are more predictable, but require patience. Search for terms like 'vintage tortoiseshell ric rac hair clip,' 'cellulose acetate barrette 1950s,' or 'British vintage hair slide.' Prices range from £15 to £45 depending on condition and rarity. A clip with intact pattern, strong spring, and no cracks is a fair purchase at the higher end. If you find one with a faded pattern but otherwise sound, you can often restore some depth by gently warming the acetate with a hairdryer on low heat—this redistributes the oils and darkens the colour slightly. Test this on an inconspicuous area first, and never overheat.

When you finally hold a Store P501, take a moment to examine the scallops. Each one was cut by hand, then smoothed and polished. The maker’s care is still there, waiting for someone to appreciate it. Clip it into your hair, and you carry that care forward.
