ステンレススチール製蓋（オリジナルmemobottle）

The silicone seal fits so snugly that I haven’t had a single drop leak in my bag since I swapped it in. The stainless steel feels cool and solid in my hand, and it’s way easier to clean than the plastic cap it replaced.

I was a little nervous the stainless steel would feel cold or slippery, but it actually has a nice weight and a smooth, secure grip. The silicone seal fits perfectly and I haven’t had a single drop leak in my bag.

The silicone seal on this lid is seriously tight—I've tossed it in my bag sideways and not a single drop leaked. Swapping it onto my bottle took two seconds and the steel feels way sturdier than the plastic cap I had before.
