The Filo Tortoiseshell Hair Clip: A Collector’s Guide to Vintage British Accessories

A vintage hair clip stamped with the word 'Filo' is a quiet signal to those who know: this is not a mass-produced modern accessory. It belongs to a small but dedicated family of British hair ornaments from the early to mid-20th century, prized for their warm tortoiseshell patterns and precise craftsmanship. For collectors, the Filo mark often appears on clips made from cellulose nitrate (early plastic) that mimics real tortoiseshell, a material that became widely used after the trade in genuine tortoiseshell was restricted. To spot a good Filo clip, you need to know how it was made, where it came from, and what details separate a keeper from a dud.

What Is a Filo Tortoiseshell Hair Clip?

The name 'Filo' appears to have been a trademark used by a British manufacturer active mainly in the 1920s and 1930s. These clips are typically small to medium-sized, designed to hold a section of hair rather than an entire updo. They feature the classic tortoiseshell pattern – a rich blend of amber, honey, and dark brown streaks – achieved through careful layering of coloured cellulose nitrate. The pattern is not printed on the surface; it runs through the material, giving each clip a unique, organic look.

Most Filo clips have a metal spring mechanism, often in a gold or silver-toned finish, that allows the clip to open and close smoothly. The springs are usually concealed inside the body of the clip, with only a small hinge visible on the back. This construction makes them comfortable to wear and less likely to snag hair compared to all-metal alternatives. The edges are polished, and the clip itself has a slight heft – not heavy, but substantial enough to feel like a quality object.

How to Identify a Genuine Filo Clip

Not every tortoiseshell clip is a Filo. Look for these distinguishing features:

• The stamp: A small, embossed 'Filo' mark is usually found on the inside of the clip, near the hinge. It may be faint after decades of wear, so a magnifying glass helps.
• Material behaviour: Genuine cellulose nitrate tortoiseshell warms up slightly in your hand and may develop a faint camphor-like smell – this is normal and indicates age, not damage.
• Pattern depth: The streaks in a real vintage clip are irregular and flow into one another. Modern imitations often have a uniform, printed pattern that looks flat.
• Spring quality: Original springs are made of steel or brass and should still snap back firmly. If the clip is loose or the spring is rusty, it may need professional repair.

The Material Story: From Real Tortoiseshell to Celluloid

The tortoiseshell look was originally achieved by using the shell of the hawksbill sea turtle, a practice that became unsustainable and was eventually banned. By the 1910s, manufacturers began experimenting with cellulose nitrate – often called 'French ivory' or 'celluloid' – to create a convincing alternative. The Filo company was part of this transition, producing clips that offered the beauty of tortoiseshell without the ethical and cost concerns of the real thing.

Cellulose nitrate has its own quirks. It is flammable (though not dangerously so in small objects) and can become brittle over time if exposed to extreme heat or direct sunlight. A well-cared-for Filo clip from the 1930s can still be used daily, but it requires gentle handling. If you notice a white bloom or a vinegar-like smell, the material may be degrading – a condition known as 'celluloid rot'. In such cases, isolate the clip from other accessories and consult a conservator.

Styling a Filo Clip with a Contemporary Wardrobe

A tortoiseshell clip from the 1920s or 1930s can feel surprisingly modern. The warm brown tones complement neutral palettes – think cream knits, camel coats, and navy blazers – as well as richer colours like burgundy and olive green. Because the clip is small, it works best as an accent rather than a statement piece. Try these ideas:

• Secure a low side-swept section of hair with the clip, leaving the rest loose for a casual, effortless look.
• Use it to fasten a silk scarf tied around a ponytail – a nod to the 1940s headscarf trend.
• Pair it with a modern tortoiseshell hair claw for a layered effect; just be mindful of mixing vintage and new materials to avoid scratching the older piece.

Caring for Your Filo Clip

Because cellulose nitrate is sensitive to environmental conditions, a few simple habits will keep your clip in good shape:

• Store away from light: Keep the clip in a dark box or a fabric pouch. UV rays accelerate yellowing and brittleness.
• Avoid moisture: Do not wear the clip while swimming or in heavy rain. Humidity can cause the surface to become cloudy.
• Clean gently: Wipe with a soft, dry cloth after each wear. For stubborn residue, use a barely damp cotton bud and dry immediately. Never use alcohol or acetone – they will dissolve the finish.
• Handle with clean hands: Oils from your skin can dull the polish over time. A quick buff with a microfiber cloth restores the shine.

If the spring becomes loose, a jeweller who works with vintage pieces can often replace or tighten it without damaging the clip body. Avoid DIY repairs with glue or pliers – they can crack the brittle cellulose nitrate.

A Final Word on Collecting

Filo clips appear at flea markets, vintage fairs, and online auctions, often priced modestly because sellers may not recognise the mark. When you find one, examine the spring action and check for cracks around the hinge. A clip with a smooth opening mechanism and no visible damage is a good buy. If the pattern has faded or the surface is scratched, gentle polishing with a specialised plastic polish (designed for cellulose nitrate) can sometimes revive it – but test on an inconspicuous area first.

Store your Filo clip in a soft, acid-free pouch away from direct sunlight, and check the spring once a year. With that simple care, it will still hold your hair in place as smoothly as it did in 1930.
