999 Yen Series Assorted Haberdashery Set French antique bobbins and lace Belding-Corticelli wooden bobbins Products bearing the name Belding-Corticelli were primarily manufactured from 1911 onwards, especially from the 1920s to the early 1930s. Those with the words "BELDING CORTICELLI" directly engraved (or beautifully printed) on the wooden spools are symbols of the "good old days of American sewing" before the switch to plastic in the 1950s. If the merged company name, Belding Corticelli, is written on them, it is highly likely that they are from the early 20th century. The "Bel-Waxed" engraving is one indicator that the product is from a specific period in the company's history (mainly around the 1920s-40s). The price of 15c is printed on the spool. This was a common practice during the late 19th to mid-20th centuries when wooden spools were the mainstream, and manufacturers often printed prices directly on the labels. Belding Corticelli spools are charming collector's items that evoke the history of the American textile industry. These are very old items, and the thread may be discolored or deteriorated and unusable. Threads from several decades ago may have deteriorated and become fragile, so rather than practical use, how about them as a vintage collection, such as for display? Rulers are not included. Thank you for viewing.
