Brain and a Finger for $12.
Limited supply. I have 10 of these sets for sale on a first come, first serve basis (orders must be paid for within 2 weeks of ordering or it will be offered up to the next person who requests). The partially eaten Brain Keychains are normally $10, but this set is being sold for $12 - the Brain would normally retail at $8 and the Severed Finger at $7, you might be only getting a few dollars in a discount, but this is for a fundraiser not a direct retail sale - so that's a pretty decent deal.
The Severed Finger will be chosen at random from a batch already made. All orders can be made here, email@example.com and mention "Brain and a Finger" as the subject - should they be all sold you, I'll let you know right away. Shipping is the same as usual, $15 in Canada, $25 in the US. Contact me for overseas rates, but be warned it won't be cheap, so best to find a couple other folks who might be interested in reduce the shipping costs.
