# Glass Hip Flasks The BARKUTAN Glass Hip Flask Has Lead-Free Glass with a Removable Leather Sleeve By Amy Duong | Published 2026-07-30 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/barkutan References: [kickstarter](https://www.kickstarter.com/projects/barkutan/worlds-first-removable-360-leather-sleeve-glass-hip-flask?ref=d02env)  The BARKUTAN Glass Hip Flask combines a lead-free glass vessel with a fully removable 360-degree top-grain leather sleeve designed to protect the bottle while preserving the flavor of its contents. Available in 100ml and 210ml capacities, the flask features a patented sleeve construction that can be removed independently of the glass, allowing damaged inserts to be replaced. Additional details include a convex viewing window, a cork-and-silicone sealed cap, a tethered closure, and a built-in label holder. The flask is designed for long-term use with replaceable glass inserts, and each package includes a spare bottle, additional cap liners, a spare wooden cap, and a cleaning kit. Personalization is available across the leather sleeve, cap, wooden cap, and snap-button tether using a selection of engraving templates. It's offered in six leather finishes.
