Glencairn glasses fit perfectly in this size

It's great for whisky

When I do blind whisky tastings, I use these to cover Glencairn glasses. It was the perfect fit for me, and it was exactly what I was looking for.

It was exactly what I expected

This is precisely what we required for our science project. They arrived undamaged and in perfect condition. The watches were well-packaged, and the watch glass was not chipped.
