ELECTRONIC WORKING LED CLOCK T-SHIRT 

LED Clock T-Shirts are operated from 4 x AAA batteries (included). Batteries will last between 12-36 hours (depending on mode) and can be replaced. Each LED Clock T-Shirt has a small hidden pack with a battery compartment, small on/off button and "mode" button (choose from digital clock or stopwatch). The battery pack connects to an electro-luminescent panel. LED Clock T-Shirts must be hand washed. Care must be taken to avoid folding the front panel and the battery pack must be removed prior to washing.
