The sizing is inconsistent, some caps fit, others don't. Even the caps that fit perfectly pop themselves off the beer when left in the fridge. I was able to get some use out of them by using the 3 that fit, and securing them with bread ties to the neck of the bottle. These might be suitable for non-carbonated drinks stored upright. They are not suited to beer.
