Nature needs hero’s. 🌲Brand new and in packaging. 12 ounces [355 ml] stainless steel thermal mug with copper vacuum insulation, stainless steel accent, clear acrylic push-on lid with swivel closure, handle, and powder coated finish. Height: 3.9”. Width: 3.5” [without handle]. Hot: 8 hours. Cold: 15 hours. The copper plating on the inner wall is an extra line of defense against temperature transfer. Heat escapes much slower so far our hot coffee stays hot even in a snow storms, and heat enters much slower so your ice water doesn’t melt even under a blistering summer sun. On average, copper vacuum insulation can make a difference of up to 9°F (5°C) over the course of 24 hours. Wash before first use. Hand wash recommended. Do not microwave. All items come from a clean, smoke-free home. 🤍
