Using these slippers is super easy. Just open the Velcro strap and slip your feet in. They're great for wearing around the house during cold winter days to keep your feet warm. When it comes to maintenance, you're in luck because they're detachable and washable. You can take them apart and toss them in the washing machine on a gentle cycle. However, make sure to let them air - dry to keep the materials in good condition. Also, try not to wear them outside as the plastic sole isn't designed for rough outdoor surfaces. Keep them indoors to ensure they last a long time and stay as cute as the day you got them.
