This refill from Double Cross Super Strong Black Putty is uniquely formulated to be stronger than anything else available on the market.

The original putty you get in the Double Cross magic trick is something that really sticks, this is the putty for you.

Can be used with Double Cross, Super Sharpie or any other application where a strong bond is needed.

This is a replacement, and you need to have the original Double Cross to use it.
