Etsy is a great place to turn up some unusual finds. Our latest favourite find is this radio shoulder bag made by seller Yeah Yeah Yes.
The maker is Taiwan based, so unfortunately the written description on the bag itself is skeletal. However, from the pictures you can see that it's shaped liked a retro radio/cassette recorder, with illustrated tape desk, speakers, and radio station display, as well as a physical knob for the radio tuner. The bag is quite substantial, measuring over 25cm wide and comes with its own shoulder strap for carrying.
You can buy one for £25.14, with an additional £7.74 for postage from Taipei to the UK.
