I’ve ordered thousands of these 29mms and they fit snugly into bigger European bottles. You need to buy the Bell Cap for closing the crown sides. The Red Baron has it.

The product arrived on time, and looks to be just what I needed, except it didn't indicate the color of the cap online. They are gold, which wasn't obvious on my computer screen.

Just the thing for capping some of the one liter and 3/4 liter wine bottles and use them for Mead which I give away.

I have bottles from all over the world, so I have to keep a few of these around. Seals the imported bottles nicely.

I needed a way to close my crown-capable Belgian (Lindemans), champagne and large format ale bottles and these caps fit them perfectly. Yes, they are slightly more expensive than the regular caps, but these caps are larger and fit all those large bottles that you couldn't use before. With these caps and the additional European capper bell that mounts on the Red Baron I instantly expanded my bottling capacity!
