The bread clip was created in 1952 by Floyd Paxton to seal his peanuts during his flight, and it became the first bread tag to effectively protect internationally baked goods from exposed air. These bread clips have other uses as well, such as categorizing wires and keeping pairs of socks together, but their job in the store ensures we get fresh bread almost every time.

Those colorful plastic labels provide guests with the freshest bread by indicating when it was stocked on the shelves — Mondays are marked with blue, Tuesdays are green, Thursdays are red, Fridays are white, and Saturdays are yellow. Wednesdays and Sundays do not have colored tags due to shipping schedules and pauses in manufacturing.

Sometimes, the bread tags even have a "best by," "sell by," or "use by" date printed on the label. Use accordingly, but keep in mind that the product is still safe to eat even after the specified date, so long as no mold is present.
