Versitile, great for filling in cracks
This works as expected. Fills in gaps well and is easy to cut. Good price. Is flexible and fills large cracks well.

Works as intended.
These have multiple uses but they work really well. The smaller size worked well for what i needed it for. 2 packs, durable and thick.

Used to fill a crack in a concrete walkway
It worked well for filling a large crack in my concrete walkway so I could top it off with the liquid crack filler.

Works great
I had to fill a small space in my window frame and this worked great. Easy to cut and just push it in any crack or space. Very easy.

Awesome
Amazon wouldn’t post my original positive review due to having the word “crack” in it. This fills cracks awesome. Amazon, do better.
