Colorful glass tiles, 4.5 cm square Red: 3 pieces Green: 4 pieces Yellow: 4 pieces Light Blue: 4 pieces Blue: 4 pieces Orange: 4 pieces One of the blue tiles has a crack. There is no crack on the back. I used these for taking photos under my handmade products when I was selling them, so they haven't been used as tiles. I would like to sell these to someone who understands the condition described above. Thank you for looking.
