They've also got a matching wallet with the same perfume print on the back, and the words "Happiness is like perfume: you can’t give it away without getting a little on yourself’ printed on the front flap. (19.5 x 10cm) £225.
And if you toodle over to the Paul Smith website, they've got both of the above plus a "key purse" (13.5 x 8cm, looks like a coin purse?) with the same perfume print and quote as the wallet. £149.
