Description from Flora and Laura
Allow your plant to drink whenever its thirsty. With the help of a funnel, fill the bulb with fresh water and place it into the mould in the flower pot. The grandmother of Samu-Jussi Koski, the creative director of Samuji, used a plastic Coca Cola bottle for the same use. Sami-Jussi decided that Samuji should create something to replace the bottle.
Made out of mouth-blown glass, the bulb should be washed gently by hand.
