They are indeed Wunderlichs and the worry about the tape is baseless. The tape they (and some others) us is plenty strong and the pads don't move at all over time, use or whatever. Just don't ask me about taking it off because I've never tried on any of my bikes. I suspect a little heat might be needed but haven't tried it.
Any pad can get worn/scuffed with time, especially if you have the ceramic fabric bits in the knees of your pants.
