Accessory 4u inc Dominican Republic Flag LED Flashing Sound Activated Light Up Shirt (Large - L)

Got these as Christmas gift for some relatives and tested them before handing them out. they seemed to work pretty well and react to sound as they are supposed to.I would recommend if you are buying them as a gift to include the batteries.I got one for myself, I havent worn it or wash it so I'll update for fabric quality once I do that.
