This pen takes forever to 'activate'--and there are two different directions: leprechan sized on the pen itself (read w my mag light) and one on the box. The box says you are supposed to shake it well (25 seconds) upright, the pen says then depress the point upright to let the 'pressure' escape? Huh? The box says not to 'overpump' the tip to fill it with paint. The TEENY print on the pen itself says to HOLD THE PENTIP DOWN  on the paper UNTIL INK FLOWS. Then of course  the pentip is supposed  'fill'  with white paint.

Well, after carefully following box and the teeny pen print directions and 15 minutes of nothing, I just held the point down on the page forever, threatening to drown it in itself, taunting it to "flow you bastard". It finally filled with white paint. Aha! But when I lifted it off the scrap paper, the tip fell out, the white went all over, and I !@#$%^. I tried another one thinking they must be old or a defective first try or I was clueless (actually I bought 2). This one blobbed all over so I used a teeny brush to pinpoint eyes on tiny drawings and on and on. I had another one in a box so I tried that one and had the exact same results.
One use with a tip brush from the blobs is all I got from THREE pens.
WORTHLESS.
Try the gel marker in white by pentel or zig instead. Even clothes markers or china markers work if they are sealed well after or waterproof clothes markers with a decent tip. Or old fashioned fountain pen ink in white.
BETTER than this waste of $. The reviewers who got them to work must be employed by the company.
Aloha
