It might not be the prettiest casing pad I've seen, but the density of the foam seems pretty nice for casing up movements. And heck, you can cut yourself out a bunch of different sizes if you'd like. I was about to throw out a scrap that was left from my last re-purposing of the anti-fatigue foam mats that I purchased at my local Chinese tool factory outlet known as Harbor Freight. Before I threw them out I gave re-purposing another thought and flashed on a case-cushion. I just traced a tin top onto it and cut it out. Again, it might not be presentable in a customer-impression setting, but it's OK on my bench, in my room. Similar mats are available elsewhere, but probably for a bit more money. Anyway, for under $10, you get at least 12 square feet of the interlocking pads. It's probably 3/8" thick. Of course it's best to cut them out before the pad has been moved around on the floor a few times. The foam is of a very nice density for many applications, IMHO. I have now used them for a rope-skipping platform, an anti-vibration pad under desk monitor-speakers, and a casing-cushion. I just thought I'd throw my not-throwing-it-out out there. Cheers.

They seem legitimate. I’m from the UK so not familiar with US associations. But what I would do if you have concerns is contact the Watch & Clock Association yourself for reassurance.
