The Trodat Printy 4912 Teacher Stamp featuring Self Assessment impression is a colourful and motivational way to allow pupils mark their school work. The self-inking stamp doesn't require a separate ink pad ensuring it is more compact and easier to store. The stamp will provide 1000's of impressions, so it will last throughout the year and beyond. The self assessment, in green ink, is not only colourful, but will be clear and easy to read. The green body not only looks great, but the stamp is also made from up to 70% of recycled material for a climate neutral product.
