Does anyone remember when you could get spy gear in the mail, or a cereal box? When agent 99 was the coolest? Well I do and i am hoping my grandson will get the fever. These Spy glasses with night vision, have LED lights that flip out. They are not only cool and fun, they are functional! These are hard pc material that is a lot like the hard material they make mobile phones out of.. Durable and lightweight. These glasses need 4 AAA batteries to work. My grandson is going ot have a blast!
