The belle-soeur strings are made to last, but a little care goes a long way in preserving the look and feel of your Studio Belle-Soeur product.

Please be aware that all belle-soeur strings are handmade and may therefore vary slightly in size, colour and design.

Kindly note that all stones are natural material and may break if dropped on hard surface.

All metal parts in the strings are made of Sterling silver 925S plated with a layer of 24 ct gold. Over time, the plating will be worn off. This is normal for gold plated products.

In order to protect your belle-soeur string, we kindly recommend avoiding that the product comes into contact with lotion, water, salt and chemicals. Also, please wipe off lotion and oil residue from your glasses before attaching your belle-soeur string to your sunglasses.

After usage, please circle your string and store it in the included fairtrade cotton bag when not wearing.

If you have any questions about our products or how to protect them, please do not hesitate to contact us via
