<p>Inspired by Dr. Seuss' <i>How the Grinch Stole Christmas</i>™, our double-walled mugs add a fun and festive touch to everything from frothy espresso drinks to cool, creamy eggnog. The two seamless walls of borosilicate glass create an insulating layer of air, so hot or cold liquids maintain the perfect temperature – yet the cup always feels cool to the touch. The set is great for holiday gift-giving or simply enjoying your favorite seasonal libations.</p> <ul> <li>Set of 2.</li> <li>Expertly crafted of mouth-blown glass with fire-polished rims.</li> <li>Grinch™ decal is applied by hand.</li> <li>Glass remains cool to the touch with hot drinks and will not "sweat" with cold drinks.</li> <li>Glass will not become cloudy over time.</li> <li>™ & © Dr. Seuss Enterprises, L.P.
