On a boat, a bottle takes abuse: salt spray, constant sun, knocks against rails, and no easy refill. The right insulated steel bottle shrugs it off. Yujie Cup supplies marine, boating, and yacht-club bottles built for life on the water.
Why marine needs steel
Plastic cracks and tastes sunny; aluminum dents and corrodes near salt. 18-8 stainless resists corrosion, won’t leach, and vacuum insulation keeps water cold through a full day on deck. Pair with our vacuum insulated bottles.
