Very small to medium-sized. This listing is for heart-shaped sea glass in green, blue, white, and brown. They are cute sizes, and many have well-defined shapes. Some with a plump thickness are also included. A 1-yen coin is placed for size comparison, so please use it as a reference (the 1-yen coin is not included). Washed and sun-dried. Please understand that these are natural items, so there may be cracks, chips, and scratches. The photos are taken in natural light, but the actual colors may differ. We will carefully package and ship the items. How about using them as materials for handmade crafts and art projects? Thank you very much. #seaglass #seaglassart #powerstone #beachcombing #handmade #accessorymaterials #aquarium
