Diffraction Plastic Rainbow Fireworks Glasses - Laserspex, Package of 8

So - obviously these rainbow symphony diffraction plastic glasses are more aesthetically pleasing than most of these type of glasses on the market - so you don't feel so out of place wearing them into public... and they do diffract. I gave them only three stars because they are 'blurry' the diffraction isn't sharp, it's like the lenses them selves came with built in fog... Now - that being said - for the price - they're still a good buy. . I'm sure the kids will enjoy them on the 4th and this seemed better than spending $20 per pair. On a side note - Once these have run their course - I won't be buying them again. . . They seem like a great beginner or starter choice to just see if the kids enjoy the fireworks more...UPDATE******************** I was the only one that kept these on for any amount of time on the 4th - while it is neat for a minute - it makes every firework look the same so . . . . . it quickly looses the appeal - just saying.
