## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    I'm hoping they hold up
  

*by L***K on Reviewed in the United States on August 21, 2019*

I used the corrugated plastic to re-enforce the walls of some custom storage boxes I made for my daughters dorm.  Finished size was 18x18x9.  They are rather large and needed to be sturdy.  I expect the plastic to hold up longer than if I used cardboard,  and is already way better than the plastic mesh sheets that I initially tried to use.  They arrived very quickly.  They are easy to cut to size.  Looking forward to finding more projects to use them with.

### ⭐⭐⭐⭐⭐ 







  
  
    Good product
  

*by R***C on Reviewed in the United States on November 11, 2019*

I purchased this to make yard signs. I used waterproof markers, sprayed the front of the signs to waterproof the writing, and then inserted wire stakes. It's been several months now, and the signs are holding up perfectly outdoors. Still look new.

### ⭐⭐⭐⭐ 







  
  
    Perfect for fabric storage
  

*by L***R on Reviewed in the United States on May 14, 2020*

I wanted something sturdy that I could wrap my fabrics around and put in a book case so that I can see what fabrics on hand.  I have seen this done with boards for comics but I wanted some sturdier.  So, I ordered these thinking I would cut each sheet into quarters.  It worked out perfectly.  I had to use a utility knife to cut them but that was fine.  Just make multiple strokes rather than trying to make the cut in one stroke and it works  out great.  I love these.
