Teachers have so many things going on in today's education system that sometimes students can get overlooked, especially in a bigger class. The Great Idea Bulb Stamp is a great way to show students that their efforts don't go unnoticed.

Reward a student with a simple stamp to show how creative and truly unique their ideas are portrayed in their work. Why buy extra ink? Your teacher stamp tool will last for numerous impressions, much longer than the ink that comes with it. Purchasing extra ink with your stamp will ensure that you will get full value from your stamp for years to come. Order ink with your stamp and don't run out of ink on the day you need it the most!
