Thank you for viewing. This is a new, unopened item. The color is silky beige. [Product Description] The "nuku2" rechargeable eco-friendly hot water bottle is cordless, so you can take it anywhere and use it repeatedly. There's no need to bother with replacing the hot water, and it only takes 15 minutes to heat up, providing warmth for up to 8 hours. You can use it as a hand warmer on your lap, as a bed warmer in your futon, or warm your feet by placing them on top of the hot water bottle like a kotatsu. It's also a great feature that the warmth lasts until morning if you heat it up for 15 minutes while taking a bath or before going to bed. The smooth flannel cover feels great against the skin, providing a soft and comfortable warmth.
