Well.. I have only bought the dolls from MiniWoo and Parabox.
MiniWoo delivery took around 14 days for me to get my parcel and it came in a form of an envelop, items in there are in perfect condition~! The total cost is slightly cheaper than Parabox.
Parabox delivery took 5 days for me to get my parcel which came in a box (thur EMS), items are nicely packed, items are in perfect condition too but the cost is abit more expensive.
