From what I know only two companies make them: Lola Jake and LikeReal.

I looked at the 'Jake website and I think they might be getting rid of the Cooper. The only have four names on the "Pack" part of the site, none of which are the Cooper; you can still find the Cooper but I had to type it into the URL myself.

Anywho, I don't know much about how people with penises urinate but I'm pretty certain you can pee just fine without pulling the foreskin back, or completely back. So I was curious about packers..

I did some research and both companies seem polarizing. I haven't heard much good about either and both products are rather expensive; over $100 each. From the sounds of it, it'd be a better bargain to just buy a Senslip.

I don't have the answer you're looking for, but I'm also curious to see if there are any uncircumcised ones. When I eventually get a packer I want it uncircumcised so I'd be interested to see if there are any around.

Have a look at the sinthetics thread, they're not a packer company but have uncircumcised prosthetic type things. I don't think anyone on here had brought one yet, and they're pretty expensive too, just not lolajake/likereal expensive. There haven't been brilliant reviews about those companies either.
For a cheap packer, Mr limpy/sailor soft pack/Mr right etc I'd just go for the senslip when I get around to buying one. Same as for an STP packer.
