I buy the sticks from my local cake store and put them in a regular size hot glue gun (for isomalt only), I have bought a few on the molds and as long as you grease the molds with the cooking spray they pop right out
I love this stuff! I will have to look when I get home as to what brand it is.
ps. when using the hot glue gun you have to make sure that you don't leave the hot glue gun on.. you push the isomalt through as it's heating up and turn it off before it gets too hot otherwise it is a HOT mess! lol if done correctly though it is a wonderful trick
