With the one-piece surround Ultimo, Karella initiates the material revolution in dart collection rings. The new, non-woven material is 100% free from harmful substances and without chemical additives. Together with the #teamkarella, the ideal composition of the high-tech materials has been worked on, so that as with conventional surrounds, misthrown darts stay perfectly stuck and thus ensure the best possible protection for the wall and floor. Insert holes almost completely disappear in the anthracite-coloured collection ring due to the special surface structure. The product is made from recycled fibres, Oeko-Tex certified, completely made in Germany and can be fully remanufactured even after several years of use. With an inner diameter of around 45 cm, the surround is suitable for all standard tournament dartboards.
