Shaped for comfort and designed for practicality, the TraVino Stemless Insulated Wine Tumbler will lovingly take care of over half a bottle of wine at a time (415ml) and keep it cool for up to 12hrs. What's neat is it'll also handle hot drinks and keep them that way for up to 6hrs. Constructed of BPA-free food grade stainless steel, the tumbler features a splashproof slide-open lid.
