Chiteki 3D Halloween Glasses-12 Pack Holiday Specs Hologram Holiday Images Turn Holiday Lights into Magical Images -Pumpkins, Skeletons, Bats,Witches (12 Pairs)

What a great invention! A huge hit with all the kids. Shouts of delight all around and the adults were impressed too.When they first arrived I thought they were a scam as I put them on in the day and could see nothing unusual. Then I re-read the instructions and tried them out on the street in the dark. Wow!!They work best when looking at small, point sources of light at a distance when it's dark. Particular fun for the kids when driving in the dark. Lots of screams and shouts of "look at that! Look over there". Will be excellent fun when trick or treating. Bought an extra pack because they went down so well and put them in party bags. All the kids loved them.You see a rainbow edged image of the bat/pumpkin etc. If you look at coloured light the main image is the same colour as the light.Wall to wall fun anyway. Highly recommend them.

Better on points of light like fairy lights at shorter range, at bigger distances can use on car lights and street lamps. Have to be distant lights to work well and corrected vision as well. Looks good to me.
