2 sumi, 4 suzuri; tools of the trade

二 墨, 四 硯, 三 硯箱 (Ni sumi, yon suzuri, san suzuribako). My grammar, etc., is probably all wrong but the picture is of 2 of my ink sticks (sumi), 4 of my favorite inkstones for grinding the ink (suzuri) and 3 ink stone boxes (suszuribako) ...

and two boxes for the 2 ink sticks, I don't know if there is a specal name for these boxes in Nihongo, in Japanese
