A tape is disclosed for use with a ball having a seam, wherein the seam has a predetermined seam color. The tape includes an adhesive layer formed of an adhesive material configured to attach to the seam, and a carrier layer formed of a carrier layer material, wherein the carrier layer has a custom color that is different than the predetermined seam color. Additionally, methods are disclosed for customizing a color of the seam of the ball using multiple tape segments. Still further, a kit is disclosed that includes the ball, a first tape having a first custom color, and a second tape having a second custom color.

A luminous leather for a sports ball includes a base fabric, a polyurethane (PU) layer, a luminous layer and a film. The base fabric, the PU layer, the luminous layer and the film are sequentially bonded by glue from bottom to top. The luminous layer is a fluorescent coating. The luminous leather for the sports ball has an enhanced luminous effect while being wear-resistant. In the new luminous leather, the luminous layer is added, and the luminous layer is a fluorescent coating. In this way, sports balls made of the new luminous leather come in different surface colors to be more entertaining. Meanwhile, a film is immediately coated onto the luminous layer by a roller before the glue gets dry to enhance the luminous effect and the color brightness, while making the entire leather more wear-resistant.

One or more aspects of the present disclosure provide articles of manufacture and components of articles that incorporate an optical element that imparts a structural color to the component or the article. The component comprises a thermoplastic polymeric material, and can include or be made to have a textured surface.

A ball chair may comprise a chair frame, a ball body and an adjusting unit. The chair frame has a connecting base and a legs base, and a supporting column formed therebetween is configured to achieve a telescopic action thereby adjusting a height of the ball chair. The connecting base is formed in a concave shape to form a housing space therein, and an annular frame is formed at an upper end of the connecting base. The ball body is configured to be coupled on the connecting base of the chair frame, and the annular frame is configured to couple with an outer periphery of the ball body thereby limiting a position thereof. As a result, the ball chair is suitable for different statures of users and enables the users to sit thereon for training or rehabilitation.

A sports ball comprising a cover disposed about a bladder is provided. The cover comprises an outer substrate and defines an outer substrate surface and a feature surface. The outer substrate surface defines a plurality of plateau sections. The feature surface is radially spaced apart from the outer substrate surface and further defines a plurality of indentations and a plurality of protrusions. Each indentation has an indentation terminus disposed on the feature surface and radially spaced apart from the outer substrate surface by an indentation depth. The protrusions are positioned on the plateau sections, and each protrusion has a protrusion terminus disposed on the feature surface and radially spaced apart from the outer substrate surface by a protrusion height. At least one protrusion is positioned less than a predetermined distance of about 1.0 millimeters from at least one of the indentations, thereby acting as a wickerbill on the ball.
