Looks to be a copy of the Foundation paints.
Don't confuse the paint with it's intended use.But Vallejo is highly pigmented already. Is there any use of this paints? I'm just wondering, because I'm buying some paints soon and I think if it's worth trying.
One question though, I read somewhere that to mix the paints better, you should put a small piece of sprue inside the bottles to aid shaking them up.
How do you do this? do the screw caps unscrew from the bottle? One of my friends seems to think not - so how do you do it?
