The Woolworths Virtual Museum says:
At the time [the 1910s] English Needles and Sewing Accessories were recognised to be the finest in the world, so naturally Woolworths bought British not only for the shops in the UK, but also for export to the United States of America and Canada, where the items were sold for five or ten cents.I found this "WOOLCO" item while helping to clean out an old house this morning. As you can see, just one sharp (a general purpose household needle) remains in the package, whose design is patented (no. 793608/34). It's difficult to decide how old this dowdy-looking package might be. The Woolco chain began in 1962, yet the Woolworth Virtual Museum shows British products, clearly pre-1962, bearing the Woolco name. I would guess that this package is, at the latest, from the 1950s.
Redditch began as a center of needle-making in the Middle Ages, soared to great industrial heights in the 19th century, and is now home to the Forge Mill Needle Museum, whose gift shop sells size 5/10 sharps.
