There is a brand new set of Terrarium figures that was just released in Japan, in October, 2019. Vol. 7 features Pikachu/Growlithe, Farfetch’d, Gardevoir, Raikou, Cleffa/Phanpy & Mewtwo.
Terrarium figures are mini figures made by Re-Ment company. They come inside a clear plastic Pokeball shaped capsule which resembles a mini terrarium.
Each figure comes in a random box with one figure and a small piece of gum. These figures are only sold in Japan and due to their popularity, they sell out very fast.
With this new series, it brings the total number of Terrarium figures to 60!!!! For those of you who arent lucky enough to live in Japan, you can still find most of them for sale on Pokevault.
