I suggest caution for now.
Kem went bankrupt. USPC bought them and is in the process of moving the plant to Cincinnati. They are expecting to be back in production by mid December.

In the final days, Kem shipped everthing they had including old lots and lots that had not gone through quality control. I had to canabalize over 30 setups (2 decks in a setup) out of 100 setups.
There is no one to complain to at this time.
Paul-Son is refusing to sell their stock of Kems unless you will accept them "AS IS."
