Coolshot glue. The beauty of this stick is if kids pour the glue on themselves it wont burn their skin (although it will still be hot enough for them not to do it again!). 7mm stick, 10cm long.
Best value is the bulk pack of 125 sticks, you can also buy a packet of 15.
Can only be used in the Coolshot glue gun.
Weight; 125 stick bulk 500 grams. 15 stick pk 65 grams.
