Custom cork?

[Sandcraig]

I’m trying to bottle with a bottle with an unusually large opening (21mm, so I’m looking for a 27mm cork). I’ve looked around but haven’t come across anyone who makes custom sized or extra large straight corks. Any ideas? Is this a fools quest that I just need to abandon?

I had some larger neck diameter bottles - thought they were wine but were likely from liquor. I got something like a t-cork for them, which fit more with what I put inbthem anyway. I opted to use them for liqueur and fortified wines that would not be finished as quickly. I am not finding them with a quick search- but it was these corks, larger diameter. MoreWine only sells the smaller, I know I had to look around
