A transportable vase holder includes a top, bottom, right-side, and left-side portions (sheets) that are pivotably connected to each other and may be positioned to form the shape of a box. At one end of the portions (the front), flaps extend from top, bottom, and side portions. Each flap is pivotably connected to the portion from which it extends such that when the top, bottom, and side portions are positioned to form the shape of a box, the flaps may be configured to keep the portions in the shape of a box. The top portion includes a slot configured to receive a vase. One flap is configured to fold over a seat belt when the vase holder is set on a vehicle seat and the seat belt is placed over the front of the holder, and thereby secure the holder in place with relative to the seat belt and seat.
