From the Flying Pig Site:
Romance and engineering in perfect harmony. Turn the handle on this delightful new model and cupid flies. Make a model for your one true love!
This is a downloadable kit. Once you purchase the kit, you download it and print it on to heavy paper (or card stock if your printer can handle it). You then just follow the instructions to cut and glue the model together. The time and effort you spend will show you really care.
