The OTR.050 HALF INCH SUPER PERMANENT INK MARKER is an alcohol based permanent marker, which fits in every pocket. The felt is very durable and the skew V shape makes tagging real fun. Of course, the marker is refillable with every kind of ink. As a very special gimmick, you’ll find a little felt cushion in the cap of the marker, which soaks up ink to a certain degree, if the marker is overly filled (prevents nasty stains in your pockets).

Refillable.
