Make the homework hustle easier with our self-inking flash stamps! Perfect for hand stamps at the end of class, or marking a homework assignment complete. Encourage great student interaction with the promise of an extra fun stamp. The lidded stacking storage bins will hold 12 stamps each.
The ink will dry very quickly on paper, and after 30 or so seconds on skin. It is recommended to give a little blow before touching inked skin.
Stamps can be used for up to 2 years, then refilled with any stamp refill ink - just put several dots directly onto the stamp material, wait 5 minutes, and blot off the excess.
