Nintendo had a great year in 2017 and it's kicking off 2018 in much the same way, with a cool range of phone cases.
There are wallet flip cases that have sticky backs which you can use on most phones, along with iPhone back cover cases, to fit the iPhone 6 and up.
The cases are based on the following games: Breath of the Wild, Splatoon and Animal Crossing. Of the Animal Crossing ones, two are flip cases and two are soft backcover iPhone cases. The other titles have only the flip cases. All look pretty well made and of course, it's cool that these are official Nintendo goods.
As for availability, the cases will only be available in Japan for the moment from the official Nintendo store - look out for their launch in April. Pricing starts from ¥2678 (RM95) for the soft cases and ¥3218 (RM115) for the Animal Crossing flipcase.
