The world’s first leather USB thumbdrive fashion accessory, apparently – that’s what the company behind these devices called them, anyway. Cosmic Blue, a storage media manufacturer that makes fashion accessory USB thumbdrives, were showcasing their products at the Premium Incentives Show in Ikebukuro. Their biggest product was a leather keychain and cell phone charm with a removable flash memory module (in models from 2 to 16GB) that allows users to replace the data portion of these fashion accessories.

Also on display were USB thumbdrives in sterling silver accessories, one with a skull and another with a “crest”, and have a loop in teh top for a pendant chain or key ring. These only come in 4GB sizes.

The company also makes some other fashion accessory/USB thumbdrive products, including a heart-shaped pendant with sixty-two 3mm cubic zirconium rocks, and another in a credit card form that the company will print two images on for you.
