These handcrafted sipper mugs are handmade with love by our friend Arielle at Best Behavior Ceramics, and Caden at Breath and Bone. Every mug is handmade and differs slightly from others, with sizing in the ballpark of 8-10oz for Breath and Bone, and 10-12 ounces for Best Behavior mugs. With subtle whispers of fun phrases underneath the fully customized glaze, the Best Behavior sipper is perfect for love month, and all year round. Breath and Bone's sipper include hand drawn doodles just in time for Valortine's Love Month, and a heart shaped sipper spout. We loveeeee them and we're sure you will too.
