The Double Mug 450 Silicone Lid from Snow Peak turns your titanium cup or mug into a beverage container suitable for traveling. The lid is made of one hundred percent durable silicone and fits the Japanese brand's Ti-Double 450 Mug. Its lip-like shape and opening make drinking particularly convenient and easy. The lid attaches lightly to the top of the mug. To clean it, simply remove it, wash it with washing-up liquid and leave it to dry. Of course, it is also dishwasher-safe.
