Crushballs can be used with both rolling filters and cigarettes. The size of the crushball is designed to fit into the end of a cigarette, but it can also be placed into a rolling filter before rolling the cigarette. Whether you prefer a slim or regular rolling filter, crushballs are compatible with both sizes.
Crushballs are designed to work universally with all types of cigarettes and rolling papers. They are compatible with various brands and types of rolling papers.
