I was either browsing through Oriental Trading's print catalog or their online site and say so many rubber duckies. I don't always stay up on the current fads now that I've retired from teaching but these rubber duckies must be popular. They have more styles than one would ever expect!
I've never ordered rubber duckies from them but I have used them for classroom incentives for the past 30+ years and their service and quality is good. The only thing I've ever disliked was the eraser on wooden pencils but that was years ago and may be improved by now.
Just one word of caution...be sure to notice the quantity in the unit sold and size measurements of the item.
