After checking out several local international grocery stores I found a set of silverware in a case designed for bentos. The set is a "My Melody" (from Hello Kitty series) set. It has adult size metal fork, spoon, and chop sticks in a reusable plastic case. The chop sticks are a little 'slippery' but I'm adjusting and they are getting easier to use. The pink case is not in your face and neither are the characters imprinted on the clear plastic lid. In other words people in the office walking by don't notice but the ones who stop to chat occasionally point and smile.
The kids were a little disappointed to find out it was for my lunches and not thiers. When the kids are a bit older and have mastered chopsticks I may buy each of them a similar set.
