Gift-giving just got smarter with this compact yet powerful 18oz. tumbler kit. Inside the bold Vibe box: a BPA-free, double-wall stainless steel tumbler with a non-slip silicone coaster, a 3.7-watt Bluetooth speaker with a mic for calls, and a 5,000mAh powerbank with dual ports. Want more sound? Swap in the 7-watt Pro Speaker for $7.25. Need light instead? Exchange the speaker or powerbank for the Beacon – an ultra-bright light with 3 modes and up to 8 hours of shine. This is an item recipients will love taking home with them!
