Review on 🛠️ Pro Project Supplies 8 Inch Composite Shims, 24 Pack - Never-Rot, High Weight Capacity, Weather Resistant. Ideal for Door, Window, and Shed Projects - Easy to Snap & DIY Home Improvement Levelers. by Ryan Vaughn

These washers are amazing! They are very durable, fold well and do not collapse under the influence of heat / humidity. We bought several of these sets because our apartment is old and the floors are uneven. They also break down into smaller pieces when needed, which is very helpful. They're a little hard to break at the thicker ends, but you just need to use some force. They also click clearly (no small splinters fly away). I will definitely buy again (and already bought).
