Fantastic service and delivery
Fantastic service and delivery. They really look after their customers. I was given some freebies as a pre order item was delayed, although it wasn’t their fault. Secure and quick delivery. Thank you! - Jack

Fantastic company ran by a fantastic individual; I’ve made 2x purchases now with Koi and both times I received a well-packaged order within 2 days of placing. 100% trusted seller with fair prices going above and beyond for their customers. 10/10 - I’ll be back to order again shortly

Fantastic customer service and price
I was lucky enough to be Koi cards first website order, and all I can say is wow. Best price for the Battle Partners booster box I'd found, incredibly fast shipping and packed with care.
They also threw in a free card sleeve and top loader for the big hit of the box - such a nice touch!
The seller is super friendly too, and someone I've chatted with a few times just about Pokémon in general, with no sales talk from them at all
Would happily recommend to anyone looking for Japanese Pokémon cards in the UK
