i recently bought gundam paint markers. but sadly they are limited in color choices so i was wondering if any other brand makes paint markers akin to what the gundam markers do. id prefer no oil based paint which is why im asking, as when i search on ebay, i only seem to get oil based 1s. as an additional question, whats the best way to store them? i dont want them to go bad some how? so im curious if i should have them standing or laying or well you tell me.
