Sea glass collected from the ocean. Sea glass is glass from broken bottles, etc., that has been smoothed by waves and sand. Collected from the sea, soaked in bleach for one day, and washed with dish soap. Perfect for handmade crafts like resin work. Please check the size and color in the images. Since it's sea glass, the product condition is listed as "has scratches and dirt." Shipping will be by an inexpensive method. I will not respond to price negotiations. Instant purchase is OK. For handmade accessories, resin art, stained glass style crafts, and science projects, etc.
