Bulk Pack of 10 - As Low As $17.50 Per Kit!
The unique flat design can be made to look like a postcard (based on an actual design that enabled radios to be sent through the mail).
The radio is assembled by soldering just two components on to a printed circuit board. The coil is 'printed' on the board and tuning is done by moving a metal plate over the coil. Batteries are not required!
Bulk pack for 10 includes: crystal earpiece, aerial wire, and self-adhesive postcard graphics.
