I haven't found many reviews on Kpopfactory but still decided to give their website a try. I ordered two BT21 bag charm doll and they are the official BT21 merch.The shipping was way faster than expected: It took about 1 week for the order to process and a week (2 at most) for it ship from SK to Canada. The shipping can get quite expensive considering it correlates to the weight of the package. However, they wrap their item very securely!
PS: They gift printed pictures for every purchase! 5/5 would recommend it.
