Master Plumber 638221 MP Plastic Toilet Shim

This product works very well. I positioned two pieces in different areas while looking at a level placed on the closed lid. The shims are very hard, which is good so that they don't compress over time. I knew that they would be very difficult to cut with a utility knife after installed, so I placed the whole shim in position and guesstimated how much I would need to cut off. I then used wire cutters to cut the shims which cut them very easily. I then tapped the shims into position gently using a screwdriver and a hammer being extra careful to not break the porcelain.

I can't get these shims to stop shifting between the bottom of the toilet and the ceramic tiled floor. I needed for the front of the toilet base only. They slip when stacked one on top of the other, offering that tiny amount of extra I needed. I am not regretful for trying this brand, but will reorder another I tried last year.

This worked to stop the rocking problem with our toilet. However, I only needed a very small portion of the tip of the shim so 90% of the product visible. The plastic is quite sturdy and I'm unsure how to cut it so that it's not visible.

None of the stores including the big box stores here in town carried these. They extendend the life of our toilet when we noticed it rocking. We never realized toilets aren't made with flat bottoms. Easy to score with an exacto knife and then snap right off. Saw how to do it on YouTube. Easy. Great product.

But they're super hard to cut. I used wire snips to cut them in the end.

Great for leveling Toilet, Shipping Fast & Great Price

We just finish putting in a new toilet. I was using wooden wedges until my son found these. They work better than wooden wedges. I even bought more for my Mother's bathroom toilet.

Bought these to shim up my toilet, and because they are plastic and won't mildew if exposed to water (very important in bathrooms!). They worked perfectly! Shipping, as always, was quick and efficient.
