I've encapsulated the blue colors of Ryukyu glass in resin, creating a slight gradation effect. There are some bumps on the back, but I hope you can enjoy them as part of the charm. They are smooth, not spiky. A necklace with an adjuster is available for an additional 50 yen (45cm x 2mm + 5cm). This is a delicate handmade item. Please handle it with care. When not in use, storing it in a container that blocks light, such as a tin box, will help preserve the color for a longer time. ◆ This is a handmade item by an amateur. Please consider purchasing if you understand this. Please refrain from purchasing if you are looking for perfection. While I create each piece with care, there may be minor initial scratches, air bubbles, dust particles, uneven surfaces, or uneven coating of the gloss finish. I hope you can enjoy the handmade texture. Please consider purchasing if you understand and appreciate handmade items. I also have other handmade items for sale. I hope you will take a look. The colors may appear different due to the photography on a smartphone. We offer secure anonymous shipping.
