I purchased my U ultra in Taiwan about 3 weeks ago. My cousin (who lives there) sent on a gift pack that I received as a result of the purchase of the phone.
It was presented nicely in a big box, (no pics cuz I asked him to dump it for shipping's sake).
Here are the items:
Case is made well, smells of rich leather. Has multiple card slots inside, with 2 larger full length slits, for folded bills, or receipts. On the rear of the case is another card slot, perfect for travel cards, or a tap and pay credit card.
Best of the three is the powerbank imo. Supports QC 3.0.
