Although the idea of budvases DUO came to me by accident (a mini bowl of MINIMAL series was drying upside down on top of another one, and I thought they looked like a nice vase), I have thought through their functionality and usability quite thoroughly. They look quite simple on the outside but there is a lot happenning inside: extra weight is added to the bottom part for stability, and also a small cylinder is attached to the base for a stem to go in, so that even a long single flower would stand straight and neat. The vases are glazed inside but left unglazed ouside, apart from the very top part where a glazed surface makes it easier to clean the possible pollen falling down.
