This replacement mouthpiece fits snugly into the straw mug, and the silicone rubber is soft enough for my toddler to chew on without damaging it. It’s nice to have a spare part available instead of tossing the whole cup.

Charlotte U. ★★★★★ Oct 19, 2026

The silicone rubber feels sturdy but flexible enough that my toddler can't bite through it, which was my biggest worry. The 58mm size fits the mug perfectly, and swapping out the old one took about ten seconds. This little piece has saved us from buying a whole new cup.

Finally found a replacement straw mouthpiece that fits perfectly and our toddler hasn't been able to bite through it yet. The silicone rubber is soft but sturdy, and it's so much easier to clean than the original.
