Genuine Flow Control Filter Cap and Metal Coffee Filter from Aeropress. Used less than 10 times. I threw away the box for the metal filter, so I will send it set in the cap. As seen in video sites and product reviews, it leaks from the boundary with the Aeropress body when you start pressing. It doesn't leak before pressing. The cap seems to have a different design from the current one. Would this be okay for those who don't mind?
