I’ve always adored little vintage boxes of Dennison and Maco red border labels and have lots in my stash of studio goodies. 
The trouble is, I never want to use them up because they’re not as easy to come by as you might think.
They can be found and purchased on Etsy and Ebay, but being so popular among crafters & designers, you know- that whole supply-and-demand-thing, the cost can be pretty hefty compared to the price of a new box back in the day.
An alternative is to simply print your own from a free download I have for you over at SC Johnson Family Economics! 
(If you leave me a comment on my SCJ Fam Ec post, you’ll make me super happy!)
Bonus: Here are a more similar label printables for you!
