This original box of Brunswick Gummed Reinforcements originally cost only 15¢ a box! These are probably from 1963 or later. (That's when the use of zip codes started).
Made by the famed Dennison Company from Framingham, Massachusetts, there is nothing better than the original!
We've not counted these to be sure that there are really 200 inside, but we suspect they are almost all there.
The entire box is original and in great shape for its age! There is some slight foxing on the corners, but not much. The cover slides easily from either side.
We still use modern reinforcements similar to these for our binder notebook pages. These vintage Dennison ones are the woven cloth reinforcements with gummed adhesive that was usually licked to activate. We suggest that you use a sponge or swab to moisten the water-activated adhesive because we cannot be sure where these traveled before they came to us.
The box measures 2-1/4 inches by 1-7/8 inch and is just over 1/4 inch high.
