These pots come in 200mm, 300mm and 400mm.
The 200mm pot can be suitable for trees at their earliest stages of Bonsai, i.e cuttings and seedlings, to Shito, Mame, and Shohin size Bonsai trees.
The 300mm is suitable for Medium sized Bonsai, i.e Komono to Katade-mochi size Bonsai trees, and the 400mm is suitable for much larger sizes like Chumono/Chiu. You can also pot smaller trees in our larger pots if you wish to eventually grow your Bonsai to that size.
