The Supply Room is one of the few places where you can find posts about Sterling Plastic. They were one of the last makers of office and school supplies in the US. Not the only one but they were one of the biggest. I still remember the Sterling Plastic school supplies in my local TG&Y. They are gone now but their items can be found on eBay and garage sales, antique stores all over the country. I have a very large collection of their office and school supplies but one item that has been missing was the #526 Roll Top Pencil Box. I have never seen it go for less than $100.00 and there have always been plenty of bidders. Now I have one. This one is used but in great shape.
This #526 is almost complete. There are three pencils with a SP# pencil sharpener and a 6" SP #525 plastic ruler. A small eraser that would be hard as a rock by now should also be in the box. The older roll top pencil boxes made by Sterling Plastic and Hasbro are very collectible. Add one to your collection.
