We know practice makes perfect right? And the Signo TSI erasable pen is brilliant for when helping someone learn to write. The Signo TSI erasable pen takes the pressure out of writing neat documents. Its erasable ink means you can correct any error –- simply use one of the two erasers on the top of the pen or cap to correct mistakes quickly and easily. Great for when the kids want to write the perfect thank you card or special letter. It works due to the thermo-sensitive ink that turns clear once enough heat is generated – so when rubbed the line is ‘erased’ and ready to write over again. This “now you see it, now you don’t” magic behind the pen should make mastering handwriting more fun. Please note that erased lines may reappear at temperatures below -18°C.It’s also amazing for precise essay writing and final drafts but obviously not suitable for legal documents. Available in black, blue, red, green, light blue, pink and violet.
