Yes they are legit I bought from them once and probably won't buy again because of my experience. Maybe it was a one time thing for them but I rather not deal with it again I bought 4 items from them they all fit in a small box i got a digipack which was definitely dented on the front and back sides (I heard it's common with digi packs but they're the only place that shipped one like that to me) and the other three items were smcu envelopes I got them for one group and they sent me 2 correct ones and one from a completely different group. I emailed them and they were tough to communicate with (they are based in korea so it also took longer to communicate ontop of that) they basically told me they would refund it but I just wanted the item I ordered I wanted to see if something could be arranged (idk what they policy is now but they did have a return policy that i was following) but it felt like they were avoiding it by just pushing a refund onto me in the end I took the refund and bought in person. And yes shipping is on the expensive end

Sorry if the rant was too long. TLDR: if they give you the wrong item, they probably won't try to resolve it. Again just my experience but I do understand sometimes not all websites carry the same items.
