Collected on the shores of Lake Biwa. Sky blue, lake blue, and other blue variety sea glass. It's very beautiful when wet. Perfect for sea glass art, accessory making, aquariums, herbariums, and interior accents! Great for summer vacation crafts too ♡ ※ Washed with water. ※ No sandblasting or polishing. ※ The one-yen coin is for size reference. Other props such as scales are not included. ※ Please take a look at my profile. Thank you! ( ◜‿◝ )♡ #BiwaGlass Thank you for viewing.
