A beautiful, simple cube with a sturdy, discrete lock on the back. I gave it to a non-profit organization that I attend that previously used a cardboard box with a donation slit cut out of the top. I pointed out to them that, by presenting a better image via a new elegant donation box, lecture attendees will respect the organization more and thus donate more. And of course they did once they put out this donation cube and got rid of the cardboard box. I gave them one of those acrylic stand up sign holders saying "donations very much appreciated" and put it next to the donation cube. It worked great. By the way, it the organization is a church or similar non-profit, get the black cube as I did; the white cube would also work. The clear cube, IMO, might work better with clarity events where people see the cube filling up with dollar bills. The black cube, on the other hand, is more discrete and better for religious and nonprofit organizations that have regular attendees.
