I never move paint directly from the bottle to the paint as I usually add some extender/retarer thinner mix to it.
Do to this I often use pallettes and or small metal trays. Transfering the paints from the trays is easy as those got small spouts or I use large pipettes.
Those metal trays I get from a friend in Japan who ships me some every few month, plus some other supplies I learned to love. Very cheap as they only cost a few cents a tray.
