كوب فينيكس معزول من الفولاذ المقاوم للصدأ

Took this camping last weekend and the copper-plated inner wall really does the job—ice cubes were still solid after six hours of direct sun. The stainless body feels sturdy in hand, not flimsy like other insulated cups I've tried.

I've been leaving one in my car during these 100-degree afternoons and the ice cubes are still perfectly intact by evening, which honestly shocked me. The copper plating inside really does make a difference with heat transfer.

Took this on a beach trip last weekend and the ice cubes were still fully intact after five hours in direct sun. The copper inner wall really does the job, and the cup feels solid without being heavy. Exactly what I needed for hot coffee on cold mornings too.
