Replacement Silicone Straws for Stanley 40 oz Adventure Tumbler, 6 Pack Reusable Food Grade Silicone Straws with Cleaning Brush, Can be Cut Off — for Stanley Cup 40 oz Water Jug Accessories, 12" Long

These are great. I like that they're silicone, because I feel safe drinking in the car, whereas a steel straw might stab me if we got into a collision mid sip. I like that they're clear so you know when they are fully clean. They just don't fit my cup. I thought a 40oz Meoky would take the same size straw as a 40oz Stanley mug, but the Meoky needs a smaller straw. Fortunately, those are also available on Amazon.

Fits great in Stanley cup , easy to clean with hot water

Love these straws! They are thick silicone so they are flexible but also sturdy and don’t just bend in the ice.

The straws works as expected, but they are just too dang fat for me. I'm returning them. It's nice that they come with cleaning brush

Delighted that these straws are the right length for my big cup.

Like most moms I’ve got my Stanley’s. Something I never thought of was how often my daughter steals my Stanley. One day my daughter grabbed it and as she turned away from my sipping on it, she fell and scraped up the roof of her mouth. This was terrifying for me and afterwards I started reading about other children that have done the same. Since I bought these straws and although I try to keep my Stanley away from her - sometimes she still gets it. I’m very happy for the quality and price of this product. It is exactly what I need!

I love these straws because they are soft and flexible, I don’t like drinking from harder straws. They fit a Stanley Cup perfectly

Perfect for 40OZ stanley
