When I saw the review list and “Mr Paint Station” and “Gunze” I was thinking this could be cool. In reality it’s not exactly what the name implies. What Mr Paint Station is actually is a holding device for painting. What you get in cellophane bag are four 3” x 5” “boxes” that are built so that the corrugation is facing out. These open corrugations then allow you to place toothpicks or other thin holding clamps you may have, into them to hold parts while they dry or perhaps when you paint them.
The cellophane bag shows that Gunze may produce a set of holding sticks that are meant to insert into the corrugation, none are supplied in the Mr Paint Station package. Unfortunately I can’t read Japanese, so I don’t know what their actual product name is or how much they cost.
