Bag charms that whiff of luxury
Posted March 5, 2007
This isn’t technically a gadget, but we love it all the same. See, Prada’s Parfum de Sac is a dinky designer vaporiser that clips on to your handbag... The aromatic accessory comes with a trio of scents from Prada’s perfume range: Intense, Classic and Tendre. Pop one inside and you'll be able to spritz while you sprint around Selfridges.
Apparently, Prada's petite perfumes will be available over at Nieman Marcus for $65 (around £34) from next month. We’ll keep you posted on UK availability. Now if only they’d redesign 'em so that they clipped on to the LG Prada phone.
