This is a fabric bowling ball bag. It holds two bowling balls and includes shoe covers. The shoe covers are sized for approximately 22-23cm. As a bonus, arm covers are also included. Using it as an inner bag for your bowling ball bag makes it easy to take balls in and out. It's also convenient when moving lanes! The bowling ball bag in the second photo has a different pattern and is not included; it's just to give you an idea of how it looks inside a carrying bag. It's a simple but durable bag, handmade with a hobby sewing machine. I use it myself and find it very convenient! Thank you.
