This is a "kensui," a container used to discard used water during the tea ceremony. It is a new, unused item, but please understand that it has been stored for a long time, so the item is old. (Please refer to my profile for details.) The box says "karakane" (唐銅), so I believe the material is karakane (bronze), but I can't decipher much else that is written. The diameter is approximately 14 cm, and the height is approximately 8.5 cm.
