Thank you for this great review! I like that you showed us a months-old pen to show how long it lasts!

And yeah I would reuse that tube if the tip can come out!

A interesting little pen for sure. If it was not for the q-tip you needed-to use with it I would say a good item to throw into your handbag 👜 but I usually don’t have any q-tips in my handbag... 👍

Very through test!
