It is the best I ever had. Super sturdy, like a small tank, and that bronze moon color, makes you want to use it. I especially like that wide nozzle , easy to fill, you don't need that silly funnel thing ... also easy to clean. Never catch rust in its inside like the cheaper ones. Like it so much I'm gonna order the other model, also 8 oz but taller , the rectangular shape one. This is a GOOD product. --- ## 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.be/products/729518124-stanley-master-unbreakable-flask-8oz-never-lose-cap-wide-mouth](https://www.desertcart.be/products/729518124-stanley-master-unbreakable-flask-8oz-never-lose-cap-wide-mouth) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-16*
