AIERSAMetal Straws for 40oz Tumbler Replacement,12 Inch Reusable Stainless Steel Straw Compatible Stanley Cup, 6pcs Large Straws with Cleaning Brush for Stanley Cup Accessories

Fit perfectly in my Stanley 40oz. Gave the straws a wash with dish soap before hand and a good rinse - no plastic aftertaste! The straw is a hard clear plastic, so it should hold up well to daily use.

great product...

Great length for big cups, durable, cute

Fit perfectly in my Stanley. Good thick material

I would recommend 2nd best silicone straw.But would like to have a silicone cap that is permanently attached. There is a better one on Amazon that has the silicone cap that is permanently attached. But if you don't want cap these are great."Doboli" no disrespect to this company and their straws is perfect for me. I like the caps so dust and knats or bugs can't get on open straw.Company was very respectful of my return. If I needed these I without caps I would buy these. I do recommend.

I was searching for a soft straw for my large cup and these are perfect! arrived on time with a nice package.

Used to replace plastic straws with silicone. Straw walls are thick so they have good mouth feel and will last a long time with repeated washings. Easy to cut with scissors to customize length. Hole diameter is large so these work well with thicker liquids like smoothies and shakes. Be aware that the diameter of these may be too big for the small holes in some containers designed for standard thin straws.

I ordered the metal one but It’s too small for my Stanley cup. On the pic is the comparison the plastic one from Stanley one.
