Sealed fine. The packaging and care into this product was nice. And the colors are so pretty. I personally think that among all safety and design features, comfort is certainly on the very top as work boots are often worn over 10+ hour days. Both audio and mic are very clear. I ship them to South Africa! Los recambios son exactamente iguales, como ya pasó con la Mi Band 4 y la 3. And the price is a lot less. THESE ARE CUTE SLIPPERS HAD TO RETURN CUZ THEY WERE TO SMALL, STRANGE BUT IT HAD KIND OF A WOBBLY BALANCE TO THEM I wear a size 11 and reviews mentioned they run large so I ordered the 9.
