WTB;WTTF GEM Push Pak blade dispenser

I'd like to buy or trade for one or two of the white plastic GEM blade dispensers that say "GEM Push-Pak" on it.  If I can't find one, I'd be interested in one of the other plain white plastic blade holders.  It doesn't matter if any of them have blades in them.  I have a lot of blades, soaps, razors, etc. that I could offer in trade or I'd buy it for a fair price.  Thanks,

Cleave
