This product is a set of "Good Job! Construction Vehicle Stickers" and the background sheet "Good Job! Construction Site" to stick them on. [If it sells well, we will restock it, so those who missed out can look for it.] Small children really love sticking stickers, don't they? My child loved cars when they were little, so I printed out homemade parking space frames and had them stick commercially available car stickers on them while toilet training. Anyway, they were so happy to stick them as a large number of cars filled the parking lot, and I still remember it. Based on that experience, I carefully created "Good Job! Parking" as a separate product. This product is a construction site version made for children who love construction vehicles. The stickers and background sheets are printed on the paper shown in the fourth image. All four background sheets are the same. Both sticker sheets are also the same. Depending on how you stick them, you can stick about 30 stickers on one background sheet. For reference, I've included an image of my child sticking them in the fifth image. I printed them with a color laser printer, but even with the margins set to the minimum, some white space remained, so I have trimmed the left and right edges of the sticker sheets slightly. I haven't trimmed the margins of the background sheets, as I thought they might be needed when used at home. You can peel off all the unnecessary parts of the sticker sheets in advance, so when you actually use them, even small children can peel off their favorite stickers themselves.
