While the burning effect of the embers looks nice, the material you receive is not the Clear plastic. I bought this expecting it to be a Variation of the flame, an ember-like flame. Rather it is an altogether different grayish/black rough looking material you’ll find nowhere in the real world. If your goal is to blend in the plastic (or perform the card prediction change) good luck!! If it is to have a nice ‘concealed’ pyro effect you’ll be fine (like from a flash pod, or from a hidden placement). The video is misleading as it shows all of the effects AS IF they are being produced from a clear plastic. Definitely will not match wrappers on card boxes, cigarette packs, candy plastic. It is grayish Black!!
Aside from that...I’m not giving the lowest rating because it IS a nice Pyro effect and I will find a way to use it. I gave a low rating though because of the misleading video and advertisement that caused me to buy something I may never use in a natural way.

I don't know if it's just the pack I got out not....I already got the green flame plastic and it was awesome...t this ember version is not the same at all... It came in still wet and it's not clear it is actually black and not cut well at all like my green one. I've very disappointed as I was actually looking more forward to this one
