Hey parents of Zak Designs Kelso tumbler users! This replacement straw kit is exactly what you need when those original straws get gross or stop working properly. You get 4 reusable silicone straws with bite valves that fit perfectly in both the 12oz and 15oz Zak Designs Kelso cups - no leaks, no fuss. The food-grade silicone is soft and safe for kids who like to chew on straws, and it won't harden over time like some cheaper options. The included cleaning brush (4.8 inches long) makes cleaning so much easier - no more struggling to get those hard-to-reach spots clean. It's actually recommended to replace straws every 2-4 months for hygiene reasons, so having this 4-pack means you're set for a year or can share with siblings. The dark green color looks great, and the quality feels solid. If you're tired of dealing with stained, cracked, or hard-to-clean straws in your kids' favorite cups, this replacement set is an absolute lifesaver that'll keep those cups in rotation much longer.
