Hi Louis,
I've been searching for such a tool for quite some time. I need to open plenty of switches to make keychains with my own keycap (a little gift for clackers who order my sleeves from Mechfashion) It's going to be very useful for me! Thanks for making these. I've had plastic, 3D printed one in the past, guess what happened 15 switches later ;-)
How much for shipping to Poland? Most likely I'm blind, but I couldn't find the price of shipping.
