This is a 4-piece set including a size 5 basketball, suitable for indoor and outdoor use, a case, and an air pump. I am not considering selling the items separately. I purchased all items from different sellers on this site. molten JB5000 (Indoor Use) I used this indoors for 1 year and 3 months. The previous owner also used it indoors, but the duration of use is unknown as it was not specified. There is a marking (printed) from the previous owner. I didn't mind the marking and used it as is. Many children use hand-me-down balls, so if you don't mind, please consider it. molten GR5 I used this outdoors for 1 year and 3 months, but the actual frequency of use was about once a month. The previous owner used it for about a year. It comes with a case, which I used as a ball case for the indoor ball. There are existing stains. Air Pump [Set Contents] Ball air pump, stainless steel air needle, Plastic air needle [Product Specifications] Size: Length 17.5cm Width 3.5cm Handle width 5.6cm Material: Plastic Color: Black Can be used for various sports balls such as soccer, basketball, volleyball, rugby, handball, netball, and yoga balls. The air needle is made of stainless steel, which is sturdy, lightweight, and easy to use. Please use whichever air needle is easier for you to use, the stainless steel or the plastic one. The air needle can be used in combination with various air pumps, hand pumps, ball pumps, bicycle pumps, etc. It is easy to handle, but children under elementary school age should use it under the guidance of a parent or guardian. I have only used the air pump 2-3 times. Both the balls and the ball case have scratches and stains. Please understand that all items are used. The balls will be deflated, and they will be shipped on weekends. Thank you for your understanding. I plan to dispose of these items soon! #Molten #Molten #Minibasket #Basketball
