The Trodat Printy 4921 self-inking stamp allows you to customise two lines of text to create a unique impression, making it ideal for loyalty and teacher stamps. Lightweight, yet durable, the compact stamp comes with its own closing cap helping to keep it neatly stored with no mess, so perfect for keeping in a pocket. An imprint size of 11 x 11 mm allows you two lines of text or an image to be personalised by you, so whether it's for rewarding customers or marking pupils work, the stamp will give you 1000's of impressions. When the ink finally begins to fade, replacement ink pads, 6/4921, can be bought to extend the use of your stamp. The colour choices include black, red, blue, green and violet.
