Yep, I was going to report back to this thread.
The flip top cap things they chose SUCK!
Regular mustard bottles would have been better.
The other day we made a light grey. Maybe a COUPLE DROPS
of black pigment in it. Got dried pigment in a bunch of prints.
Next day, 1 drop of black in a darkish green. Bunch
of dried pigment spots. I'm thinking of sending it back.
