Benro's 75mm half-ball adapter "HH75AV", brand new and unused. This adapter is for horizontally mounting a flat-base head on a 75mm diameter video tripod (bowl-type tripod). Your model is likely "HH75AVCN", but this is the same specification as the domestic version "HH75AV", so you can use it without any problems. ⚠️Important points: ・Brand new and unused. ・This is a parallel import, so it is not covered by the manufacturer's warranty in Japan. ・Please check if your tripod supports a 75mm ball before purchasing.
