Unused!! Francfranc Water Bottle Gasket Only

I don't like the spout gasket, so I won't be using it.
Therefore, I'd like to give it to someone who wants it rather than throwing it away!
Of course, it is brand new and unused.
Please rest assured!!

Thank you for looking.
There are no noticeable scratches or dirt, but please only purchase if you understand that it has been stored by an amateur.
It will be shipped with waterproofing.
Also, immediate purchase is very welcome.
I will pack it as carefully as possible and ship it quickly.
Please feel free to comment if you have any questions.
It will be first come, first served, so please consider it.
