The difference is just capacity in this case. Older versions of the Coffee Flask featured a lid with a lid that could be snapped shut as opposed to this one that twists. I hope you find this helpful. **Q: Could you eat soup out of this with a spoon ?** A: Yes, you could, but it's not ideal for soup unless you drank it from the bottle without a spoon. The mouth is about 3"wide and body is 6.5"deep. But you definitely could use it for soup. Just not sure how a spoon would work out. **Q: How tall is each size? (20oz doesn’t fit under the Keurig)** A: Hello - Mina from Tall Ridge here - Thank you for your inquiry! The 20 oz is about 9.3in which might be too tall for a Keurig. The Coffee Flask comes in three different sizes. The height of the 12 oz is 6.4in. and the height for the 16 oz is 7.9in. I hope that helps! **Q: The red lid insert molds easily. Can you get replacements for it?** A: I don’t know the answer. I did not have mold problem. Maybe because I would take the lid apart and soak it in hot sudsy water every time wash it. ## Frequently Bought Together - Hydro Flask Wide Mouth Bottle with Flex Sip Lid - Insulated Water Bottle Travel Cup Coffee Mug Black 20 oz - Hydro Flask Wide Flex Cap White 20 Oz - Hydro Flask Wide Mouth Lids- Accessory for Wide Mouth Water Bottle --- ## 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.vn/products/251780989-coffee-flask-591-ml-20-oz-vacuum-insulated-stainless-steel](https://www.desertcart.vn/products/251780989-coffee-flask-591-ml-20-oz-vacuum-insulated-stainless-steel) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-16*
