Found some at 1 of my local liquor stores. Good price too, US$1.50 each so I grabbed 2.
Looks like it holds 20oz...today I've filled it with Rogue Yellow Snow and Rockies Mojo IPA. Tomorrow, who knows?
Best regards, Bill
PS: This store also has the 750ml ceramic Rogue IMpy IPA for under US$11 bucks.
