House Points Stamps. This stamp was designed for teachers to give generic rewards for good work. It stamps an image approx 25mm x 25mm.
The stamp is supplied on a self inking machine that is available in 5 different colours - Red, Green, Violet, Blue and Black. The ink is non-toxic and lasts for ages. The ink cartridges don't dry out and when you do need to change the cartridges, you can without getting inky fingers. These stamps come with a cover so they can't get ink over the contents of bags and drawers when not in use.
