Stainless Steel bottles are a great way to tell your drink from your colleague's, your partner's and your children's drinks with nothing more than a passing glance. Custom insulated water bottles are completely leak-proof, they are made from BPA free, high-grade stainless steel and are designed especially to both keep your hot drinks warm and your cold drinks cool throughout the day, making them perfect whether you prefer a fruit smoothie or a strong coffee when you're on the go.
