Not at all happy with these. The product listing said the hole was in the big end. It is, but it also goes all the way through to the small end.

Picture is incorrect as the hole is in the small end of the stopper

I messed and got the wrong size for my original project, but after using them in an appropriate sized hole, they are holding up. I had to order a different size for the original application.

Smaller than pictured. They must have a very large hand. I would’ve taken an accurate photo however I already returned.

Be careful of your sizes. The cork industry doesn't always agree on standard sizes but these arrive as described. Good Stoppers.

Check the size charts carefully... the photo is generic and misleading. Once you have the right size the are great
