GloFXPaper Cardboard Diffraction Glasses - Great for Christmas Lights, Parties, Raves, Music Festivals, Light Shows, Fireworks

Got these for a concert and passed them out to people around me, they were a big hit and everyone loved them. I’ll definitely buy again 🙌🏼

I was gifted a pair of diffraction glasses similar to these at a music festival last summer and they made for some amazing concert experiences. If you're trying to add a crazy level of intensity to a light show, these are spectacular! This summer I need a gift for a festival I'm going to and stumbled upon these glasses when searching online. They are just the thing I was looking for and I got a good deal on them when buying in bulk. They multiply the amount of light beams you see by about 9x and also add a rainbow color effect, similar to light going through a prism. I got them just in time to hand out a bunch when seeing Tool at Boston Calling a couple weeks ago and look forward to gifting more at burns and fests over the rest of the summer.

Good good

We have a couple pairs of paper "fireworks glasses" that are 10 or 15 years old. The old glasses work with having to look directly into a light source. The rainbows appear anywhere you look. They are sharp, brilliant and plentiful.These glasses I ordered from Amazon are pretty lame in comparison. You have to look directly into a light to get a few faint rainbows - nothing like the picture shown. The kids seemed happy effort with them on the 4th of July. But I was extremely disappointed.

I haven't checked all 500 that I bought (thank you so much for selling in bulk, I'm giving them to my students) but they work as expected. The frame is thin cardboard so they'll wear out over time, but good quality given the material. I like how each one has their own individual plastic bag that they are in. It is a bit of waste of plastic, but it protects them from rubbing and scratching in packing and delivery ensuring good quality upon arrival. Definitely will buy again.

As a retired Science Teacher, I carry these in my purse wherever I go. I give them to children in grocery stories, restaurants, church, etc. (always asking permission of the adult that accompanies them--since I am a stranger) The children react with such excitement. It warms my heart. The price is a little less than I previously paid and that's a bonus too.

Great for kids of all ages! I handed them out when we went to see lights! Fun to have so many.

I bought these for an event I hosted to give out to our guests. When I tested them the effect on the were very weak. I was super hopeful because I’ve had glasses like these that were awesome, but this brand didn’t work well for us.
