Pinn's is a shop owned by Sholto Pinn, described as "the most prestigious supplier of magical artifacts in London". It's located in Piccadilly, one of the most popular shopping districts for the ruling elite, and also a victim of heavy, sometimes dangerous traffic. As well as magical artifacts, related equipment needed for certain magics are also available. It was originally a luxurious boutique, and was destroyed twice, once by Bartimaeus, then by a golem. Sales were restricted by ongoing conflicts and Sholto now works from a market barrow at the back of a tannery instead. The shop has moderate spirit activity, like most shops, guarded by competent djinn.
