Materials & Care

PVC

PVC is a strong and flexible material that doesn't tear easily. It comes in a variety of colors and thickness. While it is waterproof, it is not UV-resistant. Prolonged exposure to sunlight or heat can cause PVC to degrade more quickly. As a plastic based material, direct contact with the skin may over extended periods may lead to irritation. For this reason, PVC accessories are not recommended for daily wear.

Biothane

Biothane is a PVC-coated fabric with a TPU (thermoplastic polyurethane) finish, making it extremely durable and flexible. It is waterproof, sweat-resistant, UV-resistant, and heat-resistant—qualities that also make it suitable for animal gear. Biothane is an excellent leather alternative, both for its durability and its appearance, which closely mimics real leather. It meets REACH and RoHS certification standards for safety and environmental compliance.

Leather

The leather used by Weirdbrain is primarily sourced from recycled second-hand accessories, promoting a more sustainable approach to fashion. Because we rely on the availability of second-hand leather, our stock can vary and is not always consistently available—unlike traditional suppliers. This means certain items or colors may be produced in limited quantities depending on what materials are in stock.

Hardware

Most of the hardware used (buckles, loops, rings) is made of stainless steel. Some elements, such as heart locks and small spikes, are made from zinc alloy, while XXL spikes are made from galvanized brass. While most hardware is nickel-free, trace amounts of nickel may still be present. If you are sensitive or allergic to nickel, we recommend applying a thin layer of dermatological polish designed to prevent allergic reactions (e.g., ISOCLIP polish).

Weirdbrain is not responsible for any medical issues that may arise from wearing our accessories.

RECOMMENDED CARE INSTRUCTIONS

To keep your accessories in great condition and extend their lifespan, proper care is essential.

  • PVC tends to attract dust, fingerprints, and sweat, which is completely normal. After each wear, clean your accessory with mild soap and water, then dry it immediately using a soft, clean cloth. A microfiber cloth is especially effective for removing dust and smudges.

  • Extra care is recommended for white PVC. Unlike darker colors, white PVC shows stains very easily—such as makeup marks or sweat. If not cleaned promptly after use, these stains can become permanent and difficult to remove.

  • Biothane is easier to maintain since it's waterproof. Clean it the same way as PVC—with soap, water, and a soft cloth.

  • Avoid contact with water on metal hardware whenever possible to prevent tarnishing or corrosion over time.

  • Store your accessories away from heat and direct sunlight, especially PVC items. Remember, PVC is a plastic-based material and can warp or degrade when exposed to high temperatures (e.g., heaters, sunlight).

  • Check the screws regularly to ensure they remain tightly fastened, as they may naturally loosen over time. Use a properly sized screwdriver (flathead or Phillips) to adjust them—these can be found in any hardware store.

And most importantly, handle with care—each piece is handmade with love :)
