The bad: not my favorite packaging (tea pouches put directly in a bubble-mailer), and I hate to be picky but the matcha sampler has been just ok so far.
The good: when the packaging issue ruined a gift, Nio express-shipped a replacement so the gift would still be ready in time. I didn't even ask them to do that. So customer service wowed me. The gift was a sencha and I got to try some with the recipient and it was excellent.
