This is a new type of product for Adafruit, we want to create wearable electronics that are subtle, fun to wear and look classy. We're starting with cufflinks and soon we will have a necklace version shortly.
The cufflinks are CNC machined from the finest 6 series aluminum for durability and beauty. The iCufflinks are a remarkable accessory. Machined with a "screw in backing". Each iCufflink contains a circuit board with pulsating LED and battery.
The iCufflink pulsates for 24 hours on a single battery and costs $128. It's currently out of stock but will be available to purchase again tomorrow.
