Reasonable replica of those provided by my piano's manufacturer when piano was delivered new in 1989 and moved interstate several times thereafter. Good carpet protection--I'd look at other options for wood flooring, although these would work fine. Looks are so perfect with a black piano, you can easily ignore them.Note that, although the ABS plastic they're made of is quite tough, they might not survive under casters over 2.5" or under most double-wheeled casters, nor will they likely survive efforts to move the piano horizontally while it is sitting on them.
