This beach glass was picked by my wife and I on various beaches in the Puget Sound of the Pacific Northwest. Average size is about the same as a penny. Some smaller, some larger. Each pouch has about 40 pieces, give or take a few. These pouches are all brown glass. Each pouches glass will vary from the photo. These would be great for jewelry making, pottery, mosaics, beading, or just as decoration. Thanks for looking!
