Honestly had really hoped to get great use out of this product for marking my settings on my pedals for different songs. Bought 2 to keep an extra as the first would inevetibly run out right? I only marked 2 settings on one pedal when I bought these, and 6 months later I go to use it again and it's comepletely dried out. I kept the 2nd marker in the plastic in came in, opened it up fresh, and it's dried out as well.
Maybe my house is extra dry or something but I hoped these would last, the tops were on all the time and one was still in the plastic it was wrapped in.
Great concept, didnt work for me. Also finding it hard to get those 2 settings wiped off the one pedal 6 months later.
