Okay Stanley cup lovers, listen up! If you're tired of that one boring straw that came with your cup, we've got the perfect solution. This NINU 12-pack gives you a rainbow of colorful replacement straws that actually fit your Stanley perfectly. These aren't just any straws - they're extra long at 12 inches to reach the bottom of your 40 oz tumbler, and they create a tight seal so no leaks or spills. Made from BPA-free PP material that doesn't leave any weird taste in your drinks. Seriously, these things are durable - they last for weeks without showing wear. Each pack comes with 12 different colored straws PLUS two 12-inch cleaning brushes that actually fit all the way through. The brushes make cleaning so easy - no more gunk building up inside. Works great with Stanley cups, half gallon jugs, Mason jars, and most other big tumblers. Perfect for smoothies, water, cold drinks - you name it. Eco-friendly folks will love reducing plastic waste, and these make awesome gifts for your Stanley-obsessed friends. Pro tip: check your cup size before buying, but these should work with most 30 oz and 40 oz models.
