These are standard crown bottle tops. They work perfectly on my bottles. They arrived promptly and well packaged at a competitive price. I have tried the other crown caps with the Brew to Bottle logo but found they did not fit my bottler and had to discard them but these are great. I would recommend both the product and the seller
However, the pouches are not as strong as they could be and are suceptible to the slightest "nick" as I had a Brown ale one split on arrival but fortunately didn't lose too much and I was ready to make a brew straight away
After experiencing many types of capper over the years from hammer on to the two handle press on, I tried this and what a success so far, the effort involved has been greatly reduced to achieve the desired result. 80 caps n place already.
