So I’ve been trying to figure out if they’ve changed them because those ones are a different name and barrel but seem pretty much sane otherwise...

This is a 6 pack (no copper or pink) but you can see what the barrel looked like.

Have never had a problem with their metallic range skipping/ stopping etc or drying up, super smooth, the ink itself is a very one shade deep metallic...the gelly rolls are sort of more glittery...the shades between the brands vary too so can actually both be used for variation.

Hope you enjoy trying out whatever you get!
