Morning are rarely a blast. Unless of course you haven’t gone to bed yet. The Grenade Mug could change all that, as it replicates every outer detail of an actual grenade. Pulling the pin will not set it off, but keeping its lid closed will help keep drinks warm. If that fails and you are going to re-heat your tea or coffee in the microwave, please be sure to remove the metal pin on the lid…or you will get an explosion of a different kind.
