Thank you for viewing. This is glass for stained glass. It's leftover from use, so there are areas with magic marker residue, and small chips. I'm offering this at a low price for those who want a variety of types in small quantities, or for those who are just starting stained glass. Therefore, I am not offering discounts. I will pack carefully, but I cannot provide any guarantee in case of damage. Due to the fragile nature of the item, returns are not accepted. I hope for a pleasant transaction, so please understand and purchase accordingly.
