The flat marble set by Buki offers 150 colorful marbles in a variety of colors and effects. Alongside transparent and frosted pieces, the collection also includes glow-in-the-dark variants. With a diameter of about 2.5 centimeters each, the flat glass bodies sit comfortably in the hand. Thanks to the flattened underside, the stones do not roll away on flat surfaces, making them practical elements for crafts, table decorations, or laying games. The smooth surfaces are easy to wipe clean when needed. The set combines classic play with versatile creative applications.
