Custom Logo 32oz Leakproof Vacuum Insulated Tumbler with Straw

Frequently Asked Questions

Q: What materials are used in the 2026 Custom Logo Leakproof 32oz Tumbler and are they safe for hot and cold beverages?
A: The tumbler is made from high-grade 18/8 stainless steel, which is rust-resistant, BPA-free, and non-toxic. It is designed to safely hold both hot and cold beverages. The lid and straw are made from food-grade polypropylene and silicone, ensuring no unpleasant chemical taste.

Q: How long does the vacuum insulation keep drinks hot or cold?
A: The double-wall vacuum insulation technology keeps cold beverages cold for up to 24 hours and hot beverages hot for up to 12 hours. Actual performance may vary depending on external temperature, pre-chilling or pre-heating the tumbler, and how often the lid is opened.

Q: Is the tumbler truly leakproof? Can I put it in my bag without worrying about spills?
A: Yes, the lid features a silicone gasket and a secure screw-on design that provides a leakproof seal when closed. The removable straw has a built-in stopper to prevent leaks when the tumbler is tipped over. However, for maximum leak resistance, ensure the lid is tightly closed and the straw is properly inserted.

Q: What customization options are available for the logo on this tumbler?
A: We offer full customization including your company logo, text, or artwork. Common methods are screen printing, UV printing, or laser engraving on the stainless steel surface. Minimum order quantity (MOQ) for custom logos typically starts at 50 pieces, and our design team can assist with artwork preparation. Please contact us for specific pricing and lead times.

Q: Is the tumbler dishwasher safe? How should I clean the removable straw?
A: The stainless steel body is dishwasher safe on the top rack, but we recommend hand washing the lid and straw to prolong the life of the leakproof seal and silicone components. The straw can be cleaned using a small brush (included with bulk orders) or a standard straw cleaner. To avoid mold, ensure the straw is completely dry before reassembling.

Q: What are the shipping options and lead times for bulk orders of these tumblers?
A: For standard non-customized orders, we ship within 2-3 business days. For custom logo orders, production typically takes 7-15 business days depending on quantity and complexity. Shipping is available via air freight (5-10 days) or sea freight (20-40 days) for large orders. We offer free shipping on orders over a certain value; please check with our sales team for details.

Q: What warranty do you offer on the 32oz vacuum insulated tumbler?
A: We provide a 1-year warranty against manufacturing defects, including failure of vacuum insulation, lid breakage, or straw defects. The warranty does not cover damage from misuse, drops, or unauthorized modifications. If you encounter any issues, contact our customer service with your order number for a replacement or refund.

Q: Can I use this tumbler for carbonated beverages? Is it compatible with hot liquids like coffee?
A: Yes, it is suitable for both carbonated and non-carbonated beverages. However, do not fill the tumbler completely with carbonated drinks and leave the lid off for a few seconds to release pressure before sealing. For hot liquids, the double-wall insulation keeps the exterior cool to the touch, but avoid overfilling to prevent steam pressure buildup. The straw is not recommended for very hot beverages to avoid scalding; use the sip lid instead.
