Thank you for looking! (* ᴗ͈ˬᴗ͈)” These are empty milk cartons. They've been pre-cut for making chairs. There are 25 pieces. You can make one chair with 24 pieces, but I'll include an extra one as a bonus ♪̊̈♪̆̈ Most of them are vegetable juice cartons, but they have been bleached with Oxiclean, so there is no color or smell remaining. I apologize if I missed anything. Please understand that this is based on my amateur assessment. (* ᴗ͈ˬᴗ͈)” I may have missed something. How about using them for chair making, handicrafts, or crafts?(´˘`)ෆ˚*
