I'M NOT TELLING YOU NOT TO SMOKE
But it often happens that you go to the beach, run your hands through the sand and find cigarette butts between your fingers.
I designed this ashtray with a perforated internal container, which acts as a sieve. you get to the beach, you put some sand in it and when you smoke a cigarette you have somewhere to throw your butt. at the end of the day you just need to take out the sieve, throw away the sand and once at home or near a bin throw away all the cigarette butts accumulated during the day.
