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

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.

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.

This product is great and worked very well for an infinity mirror that I was building. My only issue is that I bought a frame that this 12x12 mirror should have fit in but this was just a little larger and I had to trim it down to get it to fit. In the process of trimming it down, I made a gash on it which is visible now but that was my fault for using a blade to try to trim it down more. I wish this would have been exactly 12x12 then I would have given this 5 stars.

UPDATE: got a replacement, and it's just as bad, if not worse. If you're using it for a magic mirror project, just bite the bullet and go with a glass one. This one is prone to bad defects.After delivery, you have to remove 3 protective films in total. This gave me confidence the acrylic would be in good condition, but upon removing the film, it had a long diagonal streak going through the middle. I thought this was maybe a scruff from me removing the protective layer, but it was in fact between layers of the acrylic, and could not be cleaned.What more, upon cleaning with ordinary windex and a lint free cloth, the reflective material began to wipe off.Poor quality and fragile. If you get it in perfect condition, install it and don't touch it. Otherwise send it back for a replacement or shop somewhere else, because it'll damage easily.

The sheet feels well made. I took the time to apply masking tape on both sides of the sheet over the cut lines before Scoring the cut. However, I was unable to prevent a crack from propagating towards the center of the usable area of my smart mirror. As a result my first encounter with this product promptly went into the trash.Second, the sheet has to be cut 1 mm less than the inner dimensions of the mounting area. If not, the sheet will distort and the reflected images will look like those in an amusement park. Therefore make sure that your seating area has enough lip to accommodate a smaller dimensions of the sheet.OK, which side is which?The manufacturer has a label on the sheet with a bar-code on it. There is clear enough information on how to identify the sides of the mirror.I like this item and ordered another one. Maybe I must use a Jigsaw this time? I wish it was a bit more inexpensive.

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!

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...

I used this to build a 6" infinity cube. It worked fine for that. It was packaged carefully and the fragile mirror side has a film attached. The acrylic cut easily.The only issue I had was one that I somewhat expected because it's only .04" thick: The pieces are a bit flexible. An infinity mirror needs fairly flat mirrors. It still works, but the reflections aren't completely straight due to very slight bends in the mirrors. I can't complain because I expected some flexibility, but if I were to make another of these I would buy the thicker version.
