It's Not Hoarding if it's Books! This mug is a celebration of all those stories we hope to get to! Back reads: There's no such thing as too many books. (We know you just need more book cases!) Great gift for a reader and book lover. This is a handmade ceramic mug created by me in my New Jersey studio. This is a stoneware mug measuring 4 x 4. Interior is a soft pink. Kiln fired, lead free glazes. Holds 16 oz. Dishwasher and microwave safe.
