i really don't think there's any thing wrong with them.
Saw them in while i was in japan, thought of buying them until i saw the price, over S$100. not sure bout the material somemore, might or might not be very good, 100% cotton?
am quite fussy with my linens, 300 thread count or more. dunno if u kids out there reading this know anything bout buying linens n thread counts but look for a higher thread count when buying bed sheets etc.
