Review: Cute and practical, but easy to misplace - These straw covers are a surprisingly useful little accessory. They fit snugly on most reusable straws and do a great job keeping dust and dirt out, especially when I’m traveling or keeping a drink in my car. The designs are cute and make it easy to tell drinks apart, which is nice for family use. They’re also easy to clean and reusable. On the downside, they’re small and easy to lose if you’re not careful. A few covers also fit a bit tighter than expected. Overall, they’re practical, fun, and a great addition if you use reusable straws often.
Review: Super Cute!! - These feel well made, especially for the price. I love the colors and they keep your straw tip covered well! They stay on and aren’t overly flimsy!
