1. Is the tumbler insulated?

Yes, our tumblers feature double-wall insulation to keep drinks hot or cold for extended periods.

2. How long will it keep drinks hot or cold?

On average, it keeps drinks hot for up to 6–8 hours and cold for up to 12–24 hours, depending on the model and conditions.

3. Is it dishwasher safe?

Most stainless steel tumblers should be hand washed to preserve insulation and finish. Always check the label or bottom of the tumbler for care instructions.

4. Can I put it in the microwave or freezer?

No. Do not microwave or freeze the tumbler. This can damage the insulation or cause cracking.

5. Is the tumbler leak-proof?

Many of our tumblers come with spill-resistant or leak-proof lids. However, they are not 100% leak-proof unless specified.

6. Is it BPA-free?

Yes, both the tumbler and lid are made from BPA-free, food-grade materials.

7. Can I use it for carbonated drinks?

Yes, but use caution. Carbonation can build pressure, especially in sealed containers. Open slowly to avoid spills.

8. Can I put it in the cup holder of my car?

Most of our tumblers are designed to fit standard cup holders, but we recommend checking the size if your vehicle has smaller holders.

9. Does the tumbler sweat or leave condensation?

No. The double-wall insulation prevents condensation, so the outside stays dry.

10. How should I clean the lid and straw (if included)?

Use warm, soapy water and a small brush or straw cleaner to clean all parts. Allow to fully air dry before reassembling.
