MultiBev Pak キャップ

I popped this on my Eddy+ bottle and the twist-to-open lid works smoothly, though the extra storage compartment isn't quite big enough for my daily vitamins. It's a handy little add-on for keeping snacks separate from my drink.

The twist-to-open mechanism clicks securely, which gives me peace of mind when tossing it in my bag with vitamins inside. Only wish the cap opening was just a tiny bit wider for easier access.

Attaching this to my existing bottle was easy, and it’s great for tossing a few vitamins in when I’m heading out. It’s a bit more secure than I expected, though I’d still prefer a slightly bigger opening for grabbing pills quickly. Works as advertised for the price.
