Postal Regret

When you post something to a social site e.g. facebook, twitter; and you regret it after a few seconds or minutes, but are too lazy to remove it. Or you just want to know the response that it will get, but eventually regret ever doing so.

I posted something onto my facebook without looking at Urban Dictionary first... and now I have postal regret.

Posca marker

An acrylic paint marker used my graphic designers, cartoonists, and anyone else looking to add mess-free bold color to their sketches.

They also take a while to activate, so the lighter colors may seem to be deficient for the first five uses.

This Posca marker is very pretty!
