These gorgeous gel ink pens (set of 2) are actually erasable! They each have a stopper on the bottom of the pen which is the eraser - and can actually erase the ink from your page! I have tested these out and they leave a very light blue mark still on the page, but I am actually really impressed with them - what a handy thing to have.
The patterns on the barrels of the pens differs slightly. Pen ink is blue.
