30ml Liquid Masking Refill (Cd)

I love this stuff, and only wish it had been around when I was a kid. This is the refill, but it comes in different pen sizes (2mm and 4mm) allowing for masking of different sized areas. The instructions state to remove within 2 days, but I recommend removing it sooner as it can become a bit difficult to remove if you wait too long. That may have to do with the degree to which it is mixed, so be sure to shake it well!
