Review: V.Good - V.Good Review: Quality over Time is questionable! - I bought and used these for just 2 months, It gets mild rusty on the mouth knob area. (Daily cleaning 2 times / day) It keeps the temperature inside the flask very stable but I'm sure it doesn't even last more than 6 months, I've used wide variety of MILTON flasks, Compared to that, quality of this flask wear off, More faster than u thought..!!

My young son uses this for school daily, we were surprised to see that it is rusting around the mouth area and cup which is very disappointing. We have other much cheaper thermos flasks that have not rusted over a much longer period of time. We will not use this item any more and will throw it away. A very big disapointment. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/414453398-thermos-stainless-steel-500ml-vacuum-insulated-bottle-with-cup-coffee](https://www.desertcart.jp/products/414453398-thermos-stainless-steel-500ml-vacuum-insulated-bottle-with-cup-coffee) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-17*
