Replacement Lids & Straws for OISIZ Bottles | From $5.99
Lids wear out. Straws get lost. It happens to the best bottles. That's why OISIZ makes genuine replacement accessories — so your favorite bottle keeps going instead of ending up in a drawer. Every accessory in this collection is designed to fit perfectly with your OISIZ bottle, maintain the same leak-proof seal, and meet the same BPA free safety standard as the original.
Whether you need a replacement lid for your Rainbow Kids Bottle, a new straw for daily use, or a fresh lid for your City-pop Tumbler 40oz — you'll find the right fit here. Starting at $5.99.
Why Genuine Accessories Matter
Third-party replacement lids and straws might seem like a shortcut — but a lid that doesn't seal correctly defeats the entire purpose of a leak-proof bottle. OISIZ accessories are made to the exact same specifications as the originals, so your bottle's seal, insulation performance, and safety standard stay exactly as they were on day one.
● Perfect Leak-Proof Seal — Every OISIZ replacement lid is engineered to the exact same fit as the original — maintaining the same leak-proof seal your OISIZ water bottle or tumbler was built with.
● 100% BPA Free — Same food-safe, BPA free materials used in the original lids and straws. No compromise on safety when it matters most — especially for kids water bottles.
● Color-Matched Lids — Rainbow Kids Bottle lids are available in 9 color options — Cherry Blossom, Azalea Pink, Sky Blue, Avocado Green, Navy Blue, Mint, Purple, Red, and UNI — so your replacement matches your bottle perfectly.
● Dishwasher Safe — Every replacement lid and straw is dishwasher safe. Same easy cleaning, same durability as the original.
● Great Value — Replacement lids from $5.99. Straws from $5.99. A fraction of the cost of a new bottle — and your bottle keeps performing exactly as it should.
