The magnetic accessory consists of two parts: the inner magnet is placed inside the desired position, while the outer magnet is attached from the outside. The two magnets attract each other with a holding force of over 2 kg, ensuring a secure connection.

Gwinis is a strong magnetic fashion accessory that reliably adheres to almost all everyday materials – e.g., clothing, hats, caps, scarves, or bags. Originally developed for Birkenstock Boston, the Gwinis stays securely in place even with friction from walking. On softer materials like clothing or bags, it provides an even stronger hold. As a general rule: the thinner and more flexible the material, the stronger the magnetic grip. For thicker materials like sheepskin or down jackets, the adhesion is somewhat reduced. Thanks to its strong magnetic force, you'll always find a suitable spot to wear your magnetic accessory securely.

Yes, you can combine as many designs as you like – just make sure that the inner magnets do not overlap.

Gwinis is designed as a lightweight magnetic accessory and is very comfortable to wear. The inner magnet is only about 2 mm thin and covered with a soft fabric layer, making it barely noticeable. If you wear your Gwinis on shoes, keep in mind that every foot is different. For sensitive feet, it might be a good idea to adjust the position in the shoe individually.

A Gwinis weighs only a few grams – you’ll barely notice it while wearing it.

The Gwinis is optimized for clogs made of 2.8–3.2 mm thick natural, oiled, or suede leather — such as Birkenstock Boston — and holds especially well on them. On shoes made from thinner materials (e.g., Clarks Originals), the holding power is even stronger. For thicker shoes like sheepskin boots, rubber boots, or rugged leather, the magnetic force is usually not sufficient for a secure hold.

Yes, your magnetic accessory holds well on fabrics like canvas (e.g., Converse Chuck Taylor, Vans Classic Slip-On, or Superga 2750) or thin leather (e.g., Clarks Originals). However, on thicker shoes like Adidas Samba, Ugg boots, or Hunter boots, the hold may be limited.

The Gwinis was developed with comfort in mind. The inner magnet is only about 2 mm thin and wrapped in soft fabric. Since every foot is different, you might find it helpful to adjust the position individually — in general, though, the magnetic accessory can be placed in a way that it doesn’t bother you.

Thanks to its slim design, the Gwinis does not impact wearing comfort. It’s extra light and barely noticeable while walking or running.

The magnetic force is very strong — the accessory can hold over 2 kg. On particularly thick materials (e.g., sheepskin), the hold may be reduced. But when attaching it, you’ll immediately feel whether the connection is secure — it works reliably on most garments.
Important: The outer part is also magnetic. If you wear the Gwinis on shoes, avoid direct contact with metallic surfaces (e.g., tables) — it could detach. When worn on bags, make sure metal objects like keys don’t stick directly to the inner magnet — this could affect the hold.

The Gwinis is water-repellent, but not completely waterproof. Light moisture won’t harm it, but it shouldn’t be exposed to prolonged wet conditions.

No, Gwinis is designed not to leave marks on most textiles. The inner magnet is enclosed in a soft textile cover that gently adheres to the material. The outer part is deliberately lightly textured to prevent slipping and ensure a strong hold. Only on very smooth leather surfaces could slight scratches occur if the Gwinis is moved back and forth forcefully.

Simply wipe it with a damp cloth — done.

No, neither the magnets nor the material are suitable for machine washing or drying.

Yes, each magnetic accessory comes with a short guide showing how to correctly attach and remove it.

Yes — we offer returns within 14 days, provided the Gwinis is unused and returned in its original packaging.
Processing returns requires a lot of time and resources — and as a small business, this is a real challenge for us.
