While browsing the $1-$3 section at my local Target (I love that section), I saw these awesome Star Wars keychains for a mere $1 each (they also had Vader and a stormtrooper). They are made of silicone, I think. I had just recently bought a vew small backpack (a sling bag) to take to work and needed some geeky accents on it and I thought these would be perfect (and CHEAP). R2 ended being too big so he now dangles from my rear view mirror in my car and the Star Wars logo is attached to my backback. I didn’t like the fact that the backs are just plain (no design) so I ended up going back and buying two more and supergluing them back to back so no matter which side they flip to, you can see what it is. I removed the chain on the Star Wars one for my backpack and left it on R2 so he can dangle.
Looks pretty good for only $2! The Space Invader is made of Perler beads my daughter made for me and the stormtrooper key chain I got at Amazon for $4 before I found the Target ones.
