Thank you for looking. These are powdered dyes for art flowers. The cases are old, but they have been stored in a dark place, so the contents are not hardened and should be fine. Brown: 1 Green: 4 Sky blue: 1 Purple: 1 Red: 1 Rhodamine: 1 Black: 1 Reddish-purple: 1 Yellow: 3 Blue: 2 These are used items stored at home. Please refrain from purchasing if you are concerned. These are leftover items from my grandmother.
