PIGMENT STK 38ML CHROMA SET/6

This is probably a dumb question, but does this paint dry fully? It looks very "wet" whenever I see artwork that's been created with pigment sticks.

Are the Painter's dozen translucent?

Can I use these with/on an acrylic painting with maybe acrylic varnish between is that possible?

Are these smaller than the ones in the 3-pack?
