In a general aspect, a multi-piece vessel can include a body defining an interior volume, and a base. The body can include a closed end, and an open end opposite the closed end. The base can have a foot arranged in a plane. The base can include a stem arranged along a longitudinal axis that is orthogonal to the plane, and a first magnetic element disposed at an end of the stem. The multi-piece vessel can also include an attachment assembly coupled with the closed end of the body, the attachment assembly having a second magnetic element configured to form a magnetic coupling with the first magnetic element, and a retention feature defined on a surface of the attachment assembly distal from the body.
