The Trodat Printy 4638 self-inking stamp allows you to customise seven 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 on your desk or in a drawer. An imprint size of 36 mm DIA allows you 7 lines of text or an image to be personalised by you, so whether it's for rewarding customers or marking a pupils work, the stamp will give you 1000's of impressions. When the ink finally begins to fade, replacement ink pads, 6/4638, can be bought to extend the use of your stamp. The colour choices include black, red, blue, green and violet.
