If you don't have a nickel allergy. *by A***T on July 29, 2026* First thing's first: I think this bottle is great. What I'm saying here is generally not a criticism. The material is listed as Stainless Steel. It takes some digging to find that it's 18/8, which means it's an alloy with 18% chromium and 8% nickel. I didn't realize this, and after using the bottle for a couple of days I had developed a really nasty cough that is still with me (greatly diminished) over a week later. Now to the rest of it. The straw lid is not fully leakproof, but it is very resistant to leak and doesn't leak quickly. The other two lids I had no issue with. All that really means is if you're gonna store the bottle sideways, don't use the straw lid. The insulation is very impressive. It was still cold after 48 hours after the bottle sat in room temperature, and after several hours sitting in an unshaded car on the hottest day of the year so far (118F heat index). Probably the biggest thing to keep in mind before purchasing is the handle. Mine hasn't broken, but many others are saying theirs has, and I can tell it's fragile. It's very nice that it comes with a straw cleaning brush, and the bottle sling is nice though the pocket doesn't really hold a phone unless you're willing to really cram it in (and I have to assume doing that a few times will cause the stitching to break). The strap is okay. ## Frequently Bought Together - Coolflask Gallon Water Bottle Insulated with Straw&3 Lids, 128 oz Water Jug Large Stainless Steel Metal Vacuum Wide Mouth for Sports, Gym or Office, Non-BPA Keep Cold 48H Hot 24H, Magic Black - Coolflask 64 oz Water Bottle Insulated with PU Leather Sleeve, Half Gallon Water Bottle Color Contrast with Straw Lids, Stainless Steel Metal Large Water Jug, Keep Cold 48h Hot 24h,Glacier White - Spout Lid Replacement for 40oz, 64oz, 87oz & 128oz Coolflask Water Bottles, Replacement Twist Lid of 2.22” Diameter, Accessories Flip lid with Big Wide Handle, Easy to Carry, Leak- Proof BPA-Free --- ## 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.jp/products/340820309-128-oz-gallon-water-bottle-insulated-with-straw-and-3](https://www.desertcart.jp/products/340820309-128-oz-gallon-water-bottle-insulated-with-straw-and-3) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-09*
