Those aren’t the same ones but similar to the ones a was referring to as well. But mine had a thinner strap behind the leg. For whatever reason if the strap is to wide or thick it bothers the back of my knees.I used to have a pair similar to these that I liked. Never been a fan of the rounded pads or ones that had a strap above the knee. All my work was interior finishes though, no rough surfaces to tear them up too bad.

Arc'teryx knee cap protectors are probably the best strap on pads....personally I prefer to have exterior knee pad pockets on my pants which generally limits me to surplus combat pants...then you have to deal with peoples comments...but they are pretty affordable and I wear out 4-5 pair a year.
Never could stand having those straps around my legs so I made something similar out of Armaflex sheet insulation. I would cut two pieces of 3/4 thick insulation 12"x20" and glue them together with Armaflex adhesive. I had two of them so I could move from one to the other when moving around on my knees. For me that worked real good.Kind of a PITA, but if you do not walk around a lot, the kneeling pads @ home depot are where it is at. When I have to kneel down, it is usually at a certain place with not much moving around. The thick (1 1/2") foam pad is really comfortable.

I am not help on knee pads.
If your selling them cheap let me know.
You have to figure out how to set the straps so they do not loosen. I like mine and have worn them all day at times but prefer the in the pants options.
