5. Are OISIZ bottles freezer safe?
Stainless Steel: We’re assuming that if you want to freeze your bottle, it’s because you want your liquids to be cold. But here’s the thing: our stainless-steel bottles are triple-layer insulated, which means that the liquids are insulated from the temperature outside of the bottle. So while yes, the bottle is technically freezer safe, we just recommend putting a few ice cubes in the bottle instead.

All our bottles feature a triple-walled, vacuum-insulated design with copper lining, ensuring your beverages stay cold for up to 24 hours and hot for up to 12 hours.

Warnings
- The straw allows generous amounts of liquid to be drawn suddenly into the mouth from the bottom of the bottle where the temperature of hot liquids is usually higher than it is at the liquid's surface.
- Drinking hot liquids presents a risk of injury.
- Hot, carbonated, and perishable liquids and other contents may build up pressure within the bottle and unexpectedly leak or spray out.

TROUBLE SHOOTING
10. Why I can't suck water from my kid's water bottle?
A couple of potential reasons for the difficulty of sucking water from the bottle.
- Air Valve on the Lid: Please take a look at the attached picture of the air valve on the lid (on the back of the lid). Ensure that there is a small hole present in the air valve. If there is no hole, this could be the reason your child is having trouble extracting water from the bottle. You can use a needle to gently clear any blockages in the air hole.
- Transparent Spout: While it’s a rare occurrence with new bottles, sometimes the transparent spout may not be positioned correctly. This typically happens when parents disassemble the spout for cleaning and then reassemble it. Please check to ensure that the spout is well-positioned. When reattaching the spout, Try applying more pressure when pushing the spout until you hear the click and notice there’s no gap between the spout and the silicone part. You should feel resistance when flipping the spout, indicating it’s fully attached.
