The Real Brands Behind Costco's Kirkland Products

4. Kirkland Signature Foil: Reynolds Aluminum Foil
Some of Costco's Kirkland collaborations aren't kept secret, but displayed proudly on the packaging. For example, if you look at Kirkland Signature Foodservice Foils, you will notice that the Reynolds logo is stamped on the front of the box. That's because the trusted aluminum foil brand partnered with Costco to help develop a quality foil for your kitchen. The main difference is that Costco offers a much bigger role for a higher price, but it's a great buy for the bulk shopper.
