Yookeer 3 Pcs Two Way Mirror Glass, 12x12x0.04 Inch Acrylic Infinity See Through Mirror Sheet for Magic Project, 30% Transparent

Arrived broken. Poorly packaged. Very expensive for what the are.

As long as you’re not expecting an expensive piece of mirror. It does it’s purpose

Perfect for infinity mirrors. Be careful if you need to cut these to size. They fracture pretty easily. And you should maybe use a diamond cutter for smooth edges. I didn’t, but it still worked out.

The material is of good quality but the price is standard for the price we pay when buying such a small quantity. We can buy from same manufacturer at the same price the seller pays. 4x8 foot sheet 3mm thick and cut to sizes we need for less than 100 use delivered.

I wanted these plastic mirrors to make an "Infinity Mirror" where these would serve as the mirror backer. Although having a perfectly flat surface was not critical for my use, I was pleasantly surprised to see these are very smooth and flat giving a true mirror reflection versus a distorted ripple image.For my application I wanted to be able to cut the sheet with a knife instead of using a saw just for simplicity. These are thin enough for me to be able to score and essentially cut with a steel ruler and a strong exacto type blade. I scored the plastic surface several times making multiple passes and was able to obtain a smooth cut/break. I snapped the scored line similar to the way one would cut glass. To do this I laid the mirror on a 1/8" thick piece of wood and using the steel ruler to hold the larger side, snapped off the excess portion. WORKED! The mirror surface is good offering a good reflection close to a glass mirror. Note that this is indeed thin and to use as a mirror you would want to support the back to keep it flat to avoid any distortion. I find this working perfect for my needs!

Decent quality, Acrylic is always prone to cracking. seems to work well, got it for a proof-of-concept project so meets the needs that I had. Long term use is unknown.
