Most hobby stores. Teachers need it to hang posters and stuff on walls without damaging them ^_^

These are all really cool combiners. Scream-o-lishor (Demoscream? Demostar?) is really cool, and that might be enough motivation for me to buy both figures  

 

Sounds gay. But thanks!

Oh you never know their potential till you've got too much free time in your hands. The power is yours!

I think Scream-o-lishor has pretty good balls compared to Devastator.

Which? Basically just put them on top of the other, if not, a little blu-tac goes a long way.

 

Cool! I just built Scream-olishor. Very nice work on this.

 

Or you could try stationery shops.

 

Movie Duocons!!! I don't have any of these figs but how 'combinable' would starscream and brawl be?? that would be a much needed upgrade for the brick that was Flywheels!!

 

Very cool! Good ideas! I love these kind of "combiners". i just wish hasbro would throw us some more of them. even though the energon cartoon was blah, i still loved the whole powerlinks idea.
