We have planned to take the money box as a household budget for our common home. Test, I have a 5 bill and some coins dropped in to see how good you can get the money. My conclusion: It takes more than patience. For Coins sure okay to give yourself problems here has to get this through the small opening. Bills go under any circumstances unless you fumbles a bit with a pair of tweezers. Too bad.
If you want to save in the long term super, because in case of doubt it helps to smash it. If you want to but they use long-term and repeatedly ran time since would not be recommended. Unfortunately
