these are full size plastic pins. there is a cap that can be removed to add water or sand for added weight. we didn't choose to do that as they were fine as/is for our needs.they include a cardboard template for pin placement. we used the template and made marks on the ground for easy pin replacement.this was exactly what we wanted. the kid versions of bowling are small. these are full size pins.
