Acrylic ice acrylic stone diamond-shaped, a set of 100 pieces in 4 colors including the new color yellow, approximately 350-360g. There are 40 clear (transparent) pieces, and 20 each of pink, yellow, and green, for a total of 100 pieces. How about using them in various ways, such as in the bathroom, toilet, living room, with houseplants, in aquariums, for children's crafts and pretend play, or as materials for terrariums and handmade crafts? I obtained them at a game center. They are unused, but there may be scratches from rubbing or initial imperfections. Thank you for your understanding.
