Used to fill voids for structural strength with a thin layer (loose aggregate) through a small hole. I attached a hard plastic tube to the (cut) end of the included cones using good quality tape. It's easy to load thick material by pouring the other end of the cylinder through a hopper. Gives a lot of pressure for a small hole. Easy to clean for reuse as all parts are unscrewable.
