Sugru mouldable glue 3-pack, black, red, white
Also available as a 5-pack in black.
This stuff is brilliant. Once you try a pack, you'll be hooked! You can use it to fix / hack anything. Take a look at my blog for some uses I've found for Sugru. This video from Sugru shows just what Sugru is:
Sugru is the world’s first mouldable glue that turns into rubber.
It all started with an idea and a small team of product designers and material scientists here in London. Our dream is to make fixing, modifying and making things easy and fun for anyone, and Sugru is our solution.
Our patented silicone technology is unique. Out of the pack, Sugru feels like play-dough, and it's that easy to use too. It bonds to almost any other material and cures just by exposing it to air. Its durable cured properties mean it'll stay strong and securely bonded anywhere from the freezer to a steamy hot shower, from the home to the great outdoors.
