I think it's more like Koh Gen Don't. They are too expensive, non-sterile and "medical grade" is meaningless, like "natural." I couldn't find any sterile cotton pads, only balls and rolls (except for gauze) anywhere.
"Intrinsics" (a product line by Carolina Beauti-Products, a subsidiary of Barnhardt Manufacturing) appears to be the only US made "medical grade" cotton pads available. This is the best price I could find:
Wipes - Esthetic, 100% Cotton, 4x4 4-ply, 200 from Intrinsics
To be honest, I seriously doubt sephora is buying Intrinsics pads when there are other options like this one:
Medical Grade Cotton - Buy Medical Grade Cotton,Absorbent Medical Cotton,High Grade Cotton Product on Alibaba.com
Ocelots like to hunt. Ocelots also like things that are round. Thank you for the suggestion, but I'll stick with my sterile cotton balls (which, of course, are no longer sterile the minute you open the package).
