Made out of sturdy plastic and strong enough to level my shed. Easy to use but it takes a little bit of effort to trim the shim. Great value.

I got these because the wooden shims kept coming out from other the leg of my washer. I have an uneven floor in the basement and it's so hard for me to adjust the feet, so I just use these. Love the way they grip. Work great and recommend.

Since I live in an apartment, I could not anchor down my safe. However, with the help of these shims as well as a weight at the back of my safe, this keeps my safe from falling and everybody safe. It is a high-quality product and performs well. The appearance is minimal as they Design and thankfully, because they are so thin, they can be a thick as you want them to be That is a great value for your money and leads to a comfort of mind.

My fridge wasn’t registering at the proper temperature it continuously was above 40 degrees and my freezer was too cold. Our floor was not level so these were the perfect solution! We used an air pump lift and put these under it not only did all the fluids regulate but they made it perfectly stable. Considering the fridge is hundreds of lbs that speaks on the quality of this item. We’ve now had them in for quite some time and I’m impressed with their performance. Great value for the money, fit perfectly in the space, excellent stability!

These things are made for a Barbie world they are so small. Maybe Ken could level his hot tub but I sure can’t!

These start from a very thin edge and work very well to shim wood structures. I even used to shim a trailer hitch to keep it from rattling!

Love these shims. Have used mostly all I bought. Will buy again when in need. Used outdoors and thought wooden shims would weaken and wear out fast. Great buy!

La partie moins épaisse permet de faire de petits ajustements. La dimension des cales est très bien pour convenir à la plupart des besoins..

They're a pain in the ass to cut and considering the price of cedar shims I really don't think these a worth it. You'll get a little bit more wooden shims for just 5$ at your local hardware store compared to 30$ for these.
