### ⭐ 1.0 out of 5 stars







  
  
    Too small
  

*by M***Y on Reviewed in the United Kingdom on 11 October 2023*

Is too small and loose fitting in the drink hole. Put straw in… immediately pushes this rubber seal through.Needs to be thicker and wider to actually work as an efficient seal.Rubbish.
