It's a launchables that includes two small rockets that are perfect for a8's or b's They each have plastic fins and go together really easily although if you aren't careful you will misalign either the preprinted graphics on the tube or the dual launch lugs if you don't pay attention. I actually had one 'creep' after I set it aside and fortunately caught it before the lugs were too far out of alignment and frozen. At any rate they are very nice little A burners etc. Real cute.
