Product Details

  • Runsip® Flex is a patented lid that is universal for cups that hold between 8 and 20 fluid ounces.
  • As stated above it is BPA free, dishwasher safe, and FDA food grade, but because it is made from a material that is approved for use in infant pacifiers, it is also microwave safe and boil safe.

  • Proudly designed, manufactured and packaged in the United States of America.
  • For best use, make sure the inside lip of a cup has a tight fit onto one of the underside rings or steps.
    • Please note that while a Runsip® Flex lid can be attached to cups that are too big to fit into the largest step or ring, the seal may not be as good.
  • To assure long term performance, try to avoid leaving lid on a cup too long and don't store it in the inverted position.


"I bought a couple for my grand kids to use at my house and I found that I love taking an easily cleanable cup and lid of water to the golf course or to play bridge."

- Margie F.  Palm Beach, FL

 "As someone who lives in California, I am always looking for ways to cut down on single-use items.  This lid has been great for me and my kids to avoid paper and plastic cups, lids and straws."

- Elizabeth M.  San Francisco, CA

 "It was hard to use at first, but after about 5 uses on different mugs and tumblers, I had it down.  It quickly became the go-to lid in our house for coffee on the way to work and school."

- Jeff M.  Austin, TX

 "I am able to fly fish a fair amount, and this lid is in my gear bag wherever I go.  Thanks."
