SOURCEONE.ORG Heavy Duty Acrylic Donation Box with Lock & Sign Holder - Secure Ballot, Fundraiser, Event Voting Container for Churches, Schools & Community Events

Yes it's small (read the description before ordering!!!), but it does the work. It is made of very good material (complete opposite to what I purchased in Staples, ugh!) Very clean, neat and sturdy. The lock is proportionally small and probably can be opened easily, but you are not going to leave this box in the middle of the night on bad neighborhood street, are you? It will be in your sight, right?I guess, it's good for coin donations. Bills, unless they are tightly rolled, are going to unfold and sneak out, which makes them easy to pull out... Still, giving it a five-star, it did the job.
