## Questions & Answers

**Q: Is this light blocking**
A: It blocks light from getting out of room and it works great.

**Q: Would I be able to use this to reflect sunlight from a fish tank?**
A: If you make the tank opaque with this in outside, yes. If please tank transparent, no. No mylar without backing would be able to do this.

**Q: Could I use this product as a “mirror” as an aisle for the wedding party to walk down on??**
A: It reflects image but is distorted

**Q: Can this be used as a studio mirror?**
A: I tried to use this as a shrink mirror.  Mounted on a 4'x8' wooden frame and tried to heat shrink it.  Tried twice, but I could not get it to shrink flat - heat gun makes it shrink, but unevenly, resulting in bumpy surface.

    Can't figure out how to hang it!
  

*by A***G on Reviewed in the United States on September 1, 2018*

Exactly what I ordered, but I really can't figure out how to hang it without a lot of work.  Not sure what to say!

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Item was as described.
  

*by S***. on Reviewed in the United States on August 21, 2018*

Item was as described, good value.  I was going to use it for practice mirrors for our chorus, but the images are not clear enough to see facial expressions.  Oh well, I tried.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works well
  

*by A***H on Reviewed in the United States on March 10, 2019*

It works well and its a steal for this price since everywhere else Ive looked is at least 2x the price and you get less.
