Direct Easy Core This body care machine uses pads attached to areas of concern on the body to deliver electrical currents, helping to train inner muscles, etc. It comes with two sets of pads, and each set uses two AAA batteries. Unused. I bought it for 2000 yen but didn't use it, so I'll sell it to someone who's interested. Shipping will be via Yu-Packet Post, with only waterproof treatment. Instant purchase is okay. Thank you for reading the description.
