These wonderful gummed stickers feature water activated adhesive - originally you'd lick these to stick them! We suggest that you use a dampened sponge because we're not completely sure of their origin.
The stickers are meant for sealing specialized documents, usually legal. Each has eight rounded or wavy corners of sorts. Each package is said to contain 1,000 pieces. While we've not counted them, we suspect that each box is full or almost full because they are packed pretty full.
Each seal measures about 3/4 inch in diameter. The box measures 2-3/8 inches square by just about 1 inch high.
These are quite a find!
