super realistic key storage stone

Stone for storing keys. I love swimming in the sea. But the problem of storing keys constantly arises. I leave all my things in the car, but where to put the car keys? I drew and printed such a secret stone and now I always carry it with me in the car. I hide the keys in it, and leave the stone outside and always find it. It is very simple and safe! For printing, I recommend MARBLE PLA. After printing, you need to insert magnets measuring 5 * 2 mm. ENJOY!
