Thank you for viewing! ^ - ^ These are natural sea glass pieces, collected one by one from the sea in Itoshima, Fukuoka. You can change the background color to your favorite! Perfect for decorating your room or as a gift! The colors appear differently depending on the light. Sea glass is glass that has been tumbled by waves, smoothing the edges and giving it a frosted appearance. It's also known as the jewels of the sea. The rounded sea glass has a strong presence, and you can even enjoy the shadows it casts! It comes with a frame, so you can display it as soon as it arrives☆ If any sea glass pieces come loose during shipping, please reattach them. I will ship it in bubble wrap. Please understand that there may be some glue residue. Thank you for your understanding! ^ - ^
