4Pcs Straw Topper for Stanley Cup, Silicone Straw Cover Cap for Stanley 30&40 Oz Tumbler with Handle, Reusable Straw Protectors, Mini Cute Stanley Straw Covers Cap for Stanley Cup Accessories (Black)

I gifted these to my niece for Christmas to top her Stanley straw at school. The colors are great and she said they fit well.

This didn’t fit my Stanley straw, very disappointed because they were really cute.
