This reusable bottle is: - 450ml - ecological, in 18/8 stainless steel, without interior coating, laser decorated, without paint and varnish - with an ergonomic 3.5cm neck that allows easy cleaning - equipped with a folding handle for easy transport - light, it weighs only 160g - single-walled, for more capacity (it is not isothermal!) - 100% waterproof, thanks to its thick seal … And above all very pretty!
