Product review (5 stars): Robot costume swag
We also bought this to make robot arms for our daughters Halloween costume.  Unfortunately while it was a cute costume, the 2 year old in her couldn't appreciate it enough to put up wit the discomfort of having semi immobile arms.  So while it did work and would serve an older child well, be mindful of those young toddlers.  They prefer running around vs the novelty of being a robot.  Ours did after ten minutes anyway.  Good for thought.  Great product though!  Easy to cut and attach to the box (we used zip ties and holes punched in the box)
