Swapping button rims?

I ordered 3 blue and 3 yellow seimitsu button and was curious how hard it would be to swap the rims so i have 3 blue buttons with yellow rims and vice versa.

Thanks in advance

It’s pretty easy. Pop a pen or something into the ‘mouth’ here to press the tab of the plunger upwards, on both sides if necessary, and the plunger will pop out.

It’s very easy, do exactly what robo said, just be super gentle. and if you don’t want to use a pen and risk getting ink on stuff, use the smallest flat head screwdriver you can find, I use the one out of my PC repair kit.
