Did you deal with them before?
Last year contacting them trying to source original iPad battery from them, from their website they claims is original and it will ship from Singapore warehouse.
Because they do not keep the item in-stock, so they can't provide any "real" photo for verification. The price is higher compare to 3rd party battery.
I'm still skeptical, as far as I'm aware, Apple never sell parts to 3rd party, all the parts from authorized repair shops are tracked.

In the end I didn't buy it from them.
