This is processed sea glass collected from the Pacific Ocean. All sea glass has been washed and sterilized. An image showing how it looks when used with a chain is uploaded. The string shown in the photo is a bonus, and will be included as a 70cm, untied piece. Please use the string as you like. The metal fitting used for the top is surgical stainless steel, which is less likely to cause allergies. If you have any questions, please feel free to ask in the comments. This is for the top only, with a bonus string. Therefore, it is listed at an affordable price. #sea #seaglass #pendanttop #seaglassnecklace
