These cozy slippers are perfect for indoor use during winter. To use them, simply slip your feet into the plush opening. They're great for walking around your bedroom or any indoor area. When it comes to maintenance, you can gently hand - wash them in cold water to keep the plush soft. Avoid using harsh detergents as they might damage the materials. Also, don't machine - dry them; instead, let them air - dry naturally. And be careful when walking on wet floors even though they're non - slip, just to be on the safe side.
