This is a very useful solution to storing used cigarette butts - until they can be disposed of in a rubbish bin. I am a smoker - but object to seeing cigarette butts just carelessly thrown on the ground; it's disgusting.
I used to have one of these - until recently - when I lost it along with my tin. Could I buy a replacement from my local supermarket - like before? No. Could I find it on Amazon - or eBay? Again - no. Eventually - after Googling - I found this place. I bought 6 of them - and even though I ended up paying more for the shipping than the actual items - they're definitely worth it.
