Huski Home travel mugs are a double whammy when it comes to being eco-friendly: not only do they replace single use take-away containers, but they also repurpose a by-product from producing coffee beans which would normally go to waste, with no residual smell or taste. These are in a generous 400ml size, double wall insulated, a have a screw-on sippy cup lid with a sealing loop, and a friction pad on the base for stability. Dishwasher safe, but avoid your microwave.
