Welly® Copper Vacuum Insulated Tumblers are fully customizable with your business logo. This beautiful tumbler is specially constructed with double-wall stainless steel which means ice cold water or juice for 24 hours or hot coffee and tea for at least 8 hours. The construction also prevents condensation on the outside of the tumbler. Comes complete with on-trend, durable powder coating and the natural bamboo wrap. It features a screw-on lid with slide closure and a wide opening for comfortable filling and pouring. No more trying to squeeze and hammer ice cubes into a narrow opening! Who needs that frustration?! And like all of our Welly promotional products 3% of the sales go toward construction of wells in areas without clean water. This is a client or employee gift with purpose in every sip! Your custom logo combined with the Welly give back program will make this a truly meaningful corporate gift, building your brand through social responsibility.
