I accidentally bought three of these, so I'm selling them. "Nighttime Crying Solution" - Popular in Europe and America! This adorable stuffed animal realistically recreates a heartbeat and warmth, providing pets with a sense of comfort as if their mother is nearby. "Easy to Use" - By placing the heartbeat box in the stuffed animal's belly, your dog can feel the sound of a heartbeat. "Skin-Friendly" - It's fluffy and feels great to the touch, making your dog sleepy. "Washable" - You can remove the heartbeat box and wash it in the washing machine if it gets dirty. "Multi-functional Toy" - Your dog can rest its chin on it, chew on it, cuddle with it, sleep with it, and enjoy it in various ways. "Set Contents" - Stuffed animal bear x 1, Heartbeat generator (batteries sold separately) x 1
