Sherman, did you read the item description?
Handmade. Japanese cypress(Hinoki) with metal ornaments. 35 by 20 by 40 cm.
She was looking for small, but I think that would be a little too
BTW, Rachel, if you are looking for portable you could always go with the old standby, a framed photograph of O Sensei that you carry around with you and hang on the wall wherever you are practing.
