These aren’t for your kids. No matter how cool, I think this will get them in trouble if they bring them to school. They are Throwing Star Push Pins!
Basically one more way to annoy your coworkers, these are throwing stars missing one corner so they can be used as normal thumb tacks. The best part is that they are only $9.99 for a set of three! I don’t know if they can be shipped in time for Christmas, but I’m going to check. You can find them here.
