These are Czech glass lampwork beads. The sizes are 12mm, 10mm, and 8mm. There may be slight variations in size due to being handmade. Although I have gathered beads of the same design, each bead is unique. I am selling these because I have too many craft supplies that I collected as a hobby and cannot use them all. I would appreciate it if you understand that these are long-term storage items. *I have a cat. I will take care when packing, but please refrain from purchasing if you are concerned.* Immediate purchase is welcome. Please refrain from price negotiations. I do not offer holds or dedicated listings. #CzechBeads #Lampwork #Assorted #Beads #BulkSale
