This is a set of changeable lens glasses from Little Tikes Stem Jr.  They call them Explorer Lens and you see different visuals when you look through them. They fit on like a scuba mask.


 They remind me of the phoroptor machine that they use at optometrists office.  They should let the kids play with these while they are there with their parents :) 

These are in played with, but good, condition and are clean and free of odors and are from a smoke-free home.

See pictures and feel free to email me for more details if needed.

Thanks for looking!
