12 x 12 x 0.04 Inch Acrylic See-Through Mirror, 30% Transparent

I used this with a laser cutter to make some perforated plastic lenses for a Halloween mask. It cut incredibly cleanly, and the plastic protective coating on both sides prevented any scratches or marring during the process.Even without the perforations, the plastic is transparent enough to see through.The only downside is that I ordered a sheet that was a little too thin and therefore it's easy to break if flexed, but that is buyer error and not the fault of the manufacturer.Can't beat the price for the quality of the material. Just remember to remove the film on each side after cutting.

The two way mirror I received came warped - I got 3 replacements, two of which had the same flaw (maybe bad luck on my side). However the vendor was extremely helpful with replacement and personally picked a mirror which was flawless. I have not had such a great customer service in a while!

The product came shattered because Amazon did not package it correctly. Amazon decided to package it in a bigger box without any material to cushion the product or to protect it from moving. The manufacture is also at fault for having a very thin bubble wrap for its packaging and a "Fragile" sticker only.

If you are looking to make a Magic Mirror this is what you want. I'll let you know the issues I had and how I overcame them. First. Even though it is acrylic do not cut it with an acrylic knife. It wont work. I tried twice and it wouldn't follow the cut when it came time to snap. What I did instead was I cut it with a dremel with the cut off wheel. Make sure the rpm isn't too high or it will melt the plastic. Second some else mentioned the waves if you get the 1mm. That is true. I was able to overcome this with using UV glue behind the mirror against the display. This makes it a permanent attachment to the display so make sure you want to go this route. To keep it pressed firmly against the LCD I placed a piece of glass over it. That will let the light through and make sure its flat. I then used the glass and a layer that will help protect the surface of the acrylic. Just make sure you wear gloves and clean the glass really well. Otherwise smudges on the inside of the glass will show. Also someone was asking what side should face the monitor and what side should face outward. The side that looks like it magnifies is the side that faces against the display. Overall it was a fun project. The last thing I would suggest is to use black electrical tape around the inside of your frame to ensure no possible light through the back.

It was too thin to be used as an electronic mirror.

This arrived in a giant box! I was so worried it was going to be broken, but it was very very bubble wrapped inside. It arrived in perfect condition. I made a huge magic mirror for a class project, and it worked out great! It's thick, but yes, you can see through it. I really enjoyed working on this project! Ended up getting a B in the class (aww ysss)! And yes, I know it's expensive. Trust me I did quite a bit of looking around and almost bought something cheap. But I think if you're going to make something for your house that you intend to use daily, or for a gift, spend the money on a quality peice of acrylic. The company even reached out to me to make sure everything was ok when it arrived. Spend the money, it's seriously worth it!Warning!! I suggest working with something a bit smaller though if you don't have the right kind of frame (like me). It tends to bow out, like it's falling out of the frame, but when I have time I plan on fixing the frame so it stays in place. Make sure you have your measurements right!! I'd suggest working with a local framing company if you'd like to put this in a shadow box type of fixture.

This is exactly as described. Works as well as to be expected. As any two-way mirror works, one side must be kept significantly dimmer than the other to appear reflective on the brighter side (the reflective material reflects about 50% and transmits the other 50%...and this works in both directions. When one side is kept dark with respect to another, significantly less light it transmitted from the dark to bright side of the mirror than is reflected from the bright side back. Thus the dark side is not perceived on the bright side, as the reflected light overpowers any transmitted light from the dark side of the mirror. The bright side also transmits 50% of it's light to the dark, and with the dark having little light reflecting from it's side, light from the bright side overpowers the reflected light and is perceived as a see-through window).I used this to make a back plate for a custom birdhouse with my daughters which we have attached to the outside of one of our home's windows. We'll see how well it works with the birds :) The challenge will be keeping the indoors darker than outdoors, particularly at night with lights on in the home...

Originally ordered the 0.12" mirror, but discovered after it arrived that I needed the 0.04" mirror. Madison provided GREAT customer service, responding very promptly to each email and helping me get the mirror I needed. The mirror is great (it's for a window bird-feeder so we can spy on the critters). If you need to cut the mirror down to size, as I did, follow the instructions in the listing, and be very very careful and very very patient. If you rush it, or don't use a very sharp tool, you could get a jagged edge. A little jagged was fine for me because the edges got covered up, but if you need a nice clean cut, PATIENCE and SHARPNESS are critical. Thanks, Madison!
