You know something is really good at the shop when kids save up their allowance for it, and then they tell two friends, and they tell two friends… and soon everyone's sporting some Spy Glasses (um, and some adults too!). The lenses are UV filtered and have mirrored outer edges that reflect the rear view image so you can see what's going on Behind you! This is sold as a little spy set with our Secret Message writing set). Great as a Birthday Party favor too.
