Had a hard time finding at the big stores

I needed some structural shims to level up a foundation that had a 1/2" slant to it. I like floors level and was not about to frame on what I was given. So both under the rim joists and under the floor joists I shimmed, and just finished the subfloor and it is almost perfectly level. It will make everything go better moving forward. I like that these are stiffer and feel substantial. They do not feel as if they will compress under a heavy load. They do make structural wooden shims, but these are more reasonably priced and I just like them better. Didn't use nearly as many as expected since I use a wood chisel to cut these, and all of the scraps then were used on the next joist. I ended up with very little waste, but then I'm kind of frugal anyway. Really glad I found these. It was perfect timing, and the leftovers I intend to use in hanging doors.

Tis shims worked perfectly for fine-tuned leveling of a large pottery fountain (about 200 lbs filled), so that water would spill evenly from opening. These were longest shims I could find -- which made them easy to work with on my particular project. Very happy with this product.
