This is a fabric bowling ball bag. It holds two bowling balls and includes a shoe cover. The shoe cover size is approximately 24cm. As a bonus, arm covers are also included (though unrelated to bowling). Using it as an inner bag for your bowling ball bag makes it easy to take things in and out and doesn't take up much space. Easy to move between lanes! The bowling ball bag in the second photo has a different pattern and is not the product itself; please see it as an example of how it looks when placed in a carry bag. It's a simple and durable bag, made with my hobby of sewing. I use it myself and find it very convenient! Thank you.
