Trek 兒童隨行杯（附矽膠吸管蓋）

The silicone straw lid seals tight enough that my toddler can toss it off the car seat without a mess, and the tapered bottom slides right into the cup holder. Even after a week of daily use, the handle has held up perfectly.

My kid loves that this cup fits right in the car’s cupholder, and the silicone straw lid has saved us from more than a few spills. The handle makes it easy for little hands to carry around too.

The tapered shape fits nicely in my car's cup holder, but the handle feels a bit small for my kid's hands. It keeps drinks from spilling for the most part, though the straw lid does leak a tiny bit if tipped over.
