I also bought the same deal (hello fellow Malaysian).
I can also confirm it’s original. I messaged the seller and he said they have a special deal going on with Acebeam factory itself. So it looks like some regional promotion for us in South-East Asia. Good for us!
They also have some other brands at good prices too, but the seller also told me that the coupons etc might not be permanent. So for those of us on Shoppee, should get it while you can.
