These red-coloured caps fit onto the Iwata suction feed jars and bottles. The caps enable you to store paints in the bottles, although if you are storing paints for long periods you will need to place something over the air-hole during storage. The name 'redi-cap' means that the bottle of paint will be ready to use next time simply by removing the cap.

If you have lost the caps from your bottles you can replace them with this pack of 20.
