Review: Totalement satisfait. J'ai commandé ce couvercle paille pour ma gourde d'une marque très connue qui n'était pas pourvue de ce système. La qualité du joint et de l'embout et des pailles que j'ai dû légèrement couper car trop longues donc parfait. Le test est totalement convainquant et je recommande ce modèle pour votre gourde qui ne sont pas pourvues de ce bouchon paille.
