I obtain flat chocolate bars and design individual candy bar covers with our logo and/or a design with a "thank you" for your contributions...etc. These can be given out as individual recognitions, or at group events. The designs can be easily changed so they are always unique. A variety of software packages can be used. I then just cut them to size on a paper cutter and tape them around the candy bars. Flat bars are easiest to use. When they are distributed, they generate smiles.
Another idea: we ordered an embosser with our logo and a "thank you" message on it that can be embossed on seals or used on envelopes and paper directly. It's an investment that's worth it, and adds class to recognition efforts.
