Noble Locks Mac Book Pro Retina 15" lock kit

I changed computers so I am selling this lock which is no longer used. The lock is great for when you want to leave your MacBook unattended in a crowded or public space and with the thefts that happen around campus, it is worth the money to be safe. It works with 15'' older generation retina models. It is as good as new, and it comes with two keys, screwdriver, and cable. I am asking for 20 but will end up selling to the best offer.
