Pilot Frixion Ball Knock Erasable Gel Ink Pens 10 Colors Set 0.5mm LFBK-230EF

It is normally a disaster if you make even a single mistake when filling out something with a ballpoint pen, but with this Frixion pen such errors are no longer an issue.
The Frixion pen is made by Japanese stationery maker Pilot, which is famous for its erasable ink. Present this pen to your children or co-workers so that they can optimize their studying / working.
Easy-to-use: you can protrude / retract the pen core by sliding down a large clip.
Simply use the back tip to erase your mistakes. The ink is designed for its color to disappear when exposed to heat by friction. As a result, it causes less damage to paper and will not generate eraser crumbs.
The Frixion pen goes perfect with a calendar: you can easily correct and update sudden schedule changes written on it.
This product contains pink, red, orange, yellow green, green, light blue, blue, purple, blue black, and black pens. These are convenient enough for decorating your writing and drawing.
