Does it mar or grip the table?** A: The bottom is made of the same metal exterior as the rest of the travel tumbler. My tumbler has not marred or gripped the table. **Q: What the height minus the lid?** A: 5.75 inches without the lid **Q: Anyone have trouble unscrewing the lid once it's been on? Got this for Christmas. Great mug otherwise, but it's extremely hard to unscrew the top.** A: I believe that a hot beverage will create a vacuum and make the lid nearly impossible to open. However, it does screw on tightly, but I don't have too much trouble getting it off. **Q: Are replacement lids available? I now have three of them with problems. They are recent purchases and fail on the slider. Almost no liquid comes out** A: I've had two which are used every week day for a couple of years and never had this problem. I hope you get some useful feedback. ## Frequently Bought Together - THERMOS ALTA SERIES Stainless Steel Tumbler, 12 Ounce, Slate - THERMOS ALTA SERIES Stainless Steel Tumbler 18 Ounce, Espresso Black - THERMOS Stainless King Vacuum-Insulated Travel Tumbler, 16 Ounce, Midnight Blue --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/184889522-alta-series-stainless-steel-tumbler-12-ounce-slate](https://www.desertcart.tn/products/184889522-alta-series-stainless-steel-tumbler-12-ounce-slate) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-26*
