List item in Shimoda

Hi, strange request for help.
I was out cycling in Izu Peninsula and just got back to Tokyo by train only to realise I left my helmet at a 7-Eleven in Shimoda.

Bit of a long shot, but if anyone is visiting in the coming weeks, would they be able to collect it for me/ ship it back to Tokyo ?

Obviously happy to cover shipping cost/ compensate for the inconvenience
