I'm a dental assistant in England, and I work for a company that USES Henry Schein most of the dental supplies.
I don't know, however, that the company can offer kimberly-clark's protective glasses. But I got my safety glasses from prakton. We use burke hart to supply our supply, but you should be able to talk to your sales staff, to see if they have, if they don't need, they should be able to find a way to get it.
