What’s a treasure for avid travelers? Of course, to get their hands on an item to keep their tea/ coffee warm on long travels. On exploring and looking up online through a number of products, I finally managed to pick the best option for my traveler son. Orpat’s kettles are of premium quality Borosilicate Glass Body making it highly durable and stain resistant. He remembers me with every sip he takes even 500 miles away.
