I thought they were a little expensive for 2 pieces of plastic but they did have a good tight fit.

We bought these to cover 2-1/2" holes we needed to put into the base of our cabinets in our winter cabin to heat water pipes during extended freeze periods. Worked very well and they fit snugly as designed. They are simple to remove when needed and fit nearly flush to the surface.
Love it!!! So soft, great length, great quality!

Used these to cover access points for the jump points I drilled in the frunk trim. Work fine, did bend back the tabs to make removal difficult if I need to jump car.

Box plainly states 2 - 2 1/2" they are not and as you can see too large to fit in and cover the floor hole that needs to be covered.

It arrived when expected, but product had a few scratches when it arrived, more obvious because its dark in colour.
