double pen BIC

The idea is quite simple, but it solves a problem I encountered as a student.

I just turned 19, and during my studies, I often found myself without a spare pen or a pen in a different color handy when the first one ran out of ink.

Thanks to this simple yet effective gadget, you save time when writing headings in a different color because the pen is already right there.

Try it out for yourself.

I recommend using two of them to hold the pens together more securely.

(Use Bic pens.)

It is recommended to print this file using TPU.
