ScurtainUnisex Adults Rubber Sole Slippers

Q: What country manufactured?

I don't know what country. And it matters to me as well because of forced labor. The non skid soles are wonderful for those at risk of slips / falls. Nursing home residents. They also wear well with washing. Air dry.

Q: Are these slippers washable and dryable?

My grand daughter wears hers everywhere!! Even mud holes on occasion. They always wash and are just like new!

Q: Do you wash these on the regular cycle or delicate cycle or must you hand wash them? Also, do they need to be washed separately from other items?

Put them on regular wash cycle. Do not dry in dryer.

Q: Why do they call it black/air hole?

It is merely a translation failure. "BLACK" because that is the color / "AIR HOLE" is attempting to explain the "breathable venting hole on the toe-cap to keep your feet comfortable all the day." These shoes are super comfy and yes, they breathe well.
