### ⭐⭐⭐⭐⭐ Works great
*by J***T on May 24, 2025*

No swelling like wood shims. Great for wet conditions

### ⭐⭐⭐⭐⭐ Extremely Useful
*by S***N on August 24, 2024*

These are way more useful than I expected. I use them for everything now. I bought them as a Tremolo Wedge for my guitar while tuning. But they are so adaptable .. and you get so many of them, I just run around the house leveling things and filling gaps. Easily snapped to the size you need, and gaff taped together to make them thicker.
