Interesting. I’m not sure I’ve seen those in europe. Are they standard hotel mini-bar bottles? I don’t drink and I’m pretty sure they don‘t sell them in sweden‘s state liquor store.
60ml would be a useful size 👍
You can find the new empty bottles for pretty cheap on amazon. Not sure about sale in europe or shipping to there, but I'd guess it wouldn't be a problem. A google search for "empty mini liquor bottle" should turn up quite a few hits.
