What size rubber bands work best?

If you're using a regular 4.5x3/8" wooden craft stick, then the best rubber bands are 3.5x1/8" (size #33) rubber bands. Two rubber bands usually works best!

How many propeller are in one pack? And how many pack is being given here in this order?

There are 10 propellers in a pack. If you order one of this item, you'll receive one pack.

What kinds of plastic is this made from?

I am not positive but these worked great for our classroom to make propeller cars. Much more sturdy than the propellers we used previously.
