FORMA - concrete vase | decorative object concrete | organic concrete vase | concrete decor | large concrete vase | large concrete vase | sculpted concrete vase. Dimensions: 14 cm x 14 cm x 30 cm (height). Note: Because all the pieces are handmade and because of the nature of concrete, no two pieces are exactly the same. Each piece has slight variations (i.e. air bubbles and color). No concrete casting is 100% free of bubbles/blemishes, but that adds to its charm and character! Materials: water, non-toxic pigment, concrete.
