DUNLOPMens Slippers Slip On Comfy Twin Gusset Rubber Sole Washable Sizes 7-12

Could you please inform me as to the country of manufacture of these slippers?

Are these slippers machine washable?

I'm a UK size 9 / 9.5. Are these slippers generally a small or large fit?

Ordered men's slippers on 16 March 22 (payment taken 17 March 22) - when can I expect delivery ??
