LifeStraw Peak Series Solo 替換蓋

The threads seat cleanly on my Peak Solo filter, no wobble. They’re plain BPA-free plastic, which is fine, but I wish they’d come as a two-pack for the price. Still, knowing a kid gets clean water with each order makes it easier to swallow.

The caps fit my filter perfectly, but I wish the two-pack came with a few more for the price. The BPA-free plastic feels sturdy enough, and I like that the purchase goes toward water charity, just not sure it's the best value.
