It is small. You could put three balls and 3 tees. It is useful.Looked like description-gave as gift so I can’t really help any furtherFits on bag. Like that it’s easy to get your tees if your bag doesn’t already have an outer holder for them.Not what I expected from the pictures of the product.I didn't expect this sleeve to be as functionally good as it really is. The flex in the material is perfect to hold balls and never fall out on the course but easy to remove one handed from either the top or bottom.The tee holders in the side USUALY keep hold but some have occasionally fallen out (maybe 5 tees lost in 30 rounds of golf). Not a deal breaker.
