MESHU's Space Travel Gel Pen has a patterned design and unique erasable ink.
The blue gel ink not only writes brightly on paper, but also becomes invisible when exposed to temperature. It is enough to rub the writing with the eraser on the tip of the pen.
At low temperatures, the invisible ink reappears.
