Easily change between left and right handed orientation by pushing down on the lid and turning right. The large soft grip handle includes scratch-resistant silicone for the most comfortable hold ever. Keep your mug right where you left it with the non-slip rubber base that even your sneaky cat can’t knock it over. Take your new mug with you with the non-slip rubber base. When you’re ready to clean, put your mug on the top rack dishwasher.
