Frequently Asked Questions
Are these tumblers truly leakproof for car use?
Yes — the Era series uses a patent‑pending U‑Turn lid designed to be leakproof even with carbonated beverages. That makes them a strong option for in‑car use, though you should always ensure the lid is locked and the straw position is closed before driving.
Will these tumblers fit my car's cup holder?
Most Era tumblers have a tapered, cup‑holder‑friendly base designed to seat in standard vehicle cup holders. If you have an unusually small or extra‑deep cup well, measure the diameter and compare to the product dimensions to confirm fit.
How do I clean the lids and straws?
Lids and straws are top‑rack dishwasher safe; most bodies are dishwasher safe too depending on finish. For best results, disassemble the lid and straw components and run them on the top rack or hand‑wash small parts to remove residue from the U‑Turn channel and straw mounting.
