There are three variants when it comes to the print you find on them. One features the series’ mascot Rathalos, another features a Felyne print, and a third featuring the Monster Hunter crest in the game’s distinct art style.
They also come with an SD card adapter with matching prints. Special prints aside, these microSD cards are all identical since they are all 16GB Class-10 cards. These Monster Hunter 15th anniversary microSD cards are priced at JPY1980 (~RM72) each and will be released on 25 April in Japan. That said, we don’t think that these special edition cards will make their way out of their home country, let alone on our shores. (Source: Honma [pdf] via Siliconera // E-Capcom Store – 1, 2, 3)
