I cut and placed two layers in a pair of safety goggles for health class, making them similar to "drunk" goggles. Worked well, fingerprints are easily made handling these.

I purchased these diffraction films to use as prisms to cast giant rainbows on my wall, they worked perfectly for that purpose!

Each sheet is full of nicks, it's not protected when they ship it. So it's useless when it arrives. Very disappointing

This diffraction film came rolled up and taped , with three different pieces of tape , one piece was completely un-usable it had tape residue on it, and I ordered 5sheets but I only received 4.

Was sent in a polymailer without a cardboard envelope or tube. Disappointing as it is very important that this film not have ridges that make it more difficult to use.. which is what the ridges caused.

Glued one to my 3d printer bed to transfer the pattern onto the prints.
