Steve,
I found out that Sharpie pens are alcohol-based, however, these pens
are susceptable to drying out without the cap. Would the print sponge
pad be enough of a "cap" to prevent this?
Secondly, anyone here happen to know the compoistion of Staedtler Red
Lumocolor Permanent Pens? I understand that they are dry-proof, but I
wonder what is based of.
