The Uni-ball Signo TSI is an erasable rollerball pen that contains a brand new erasable ink formula.ﾠ
The pen's name, TSI, refers to its ink which is known as Thermo Sensitive Ink. This type of ink changes from a coloured ink to a clear ink when heat is applied, effectively erasing the ink. It can then be written over using the same pen.
To erase the ink, you can use either the eraser at the end of the barrel or the one on the end of the cap and give it a good rub over the ink to make sure it has completely gone. Because it is thermo sensitive ink it can reappear if subjected to very low temperatures below -18 C.
The Uni-Ball Signo TSI Erasable rollerball pen has a 0.7mm tip that writes a 0.5mm line. There are seven vibrant ink colours to choose from.
Uni-Ball TSI pens are also known by their part no as Uni-Ball UF-220-07 erasable gel rollerball pens.
Available individually or further savings can be made buying in packs of 12.
