The Carall Greenland Car Air Freshener by far is one of the best smelling scent any car can have. However the biggest drawback is that the 13g chalk stick that produces the fragrance always melts into the vent clip, rendering the clip to become a one-time use only. Additionally, the vent clip doesn't fits all car models and the clip breaks after several uses.

This case is custom designed to fit the 13g chalk stick, to maximize the exposure to environment, making the fragrance stronger. It also doesn't require any clipping, but just a string or rubber band can be used to be hung on the rear view mirror or any parts of the car you deem.

The screw on case means that swapping out for new scent sticks is easy. Hole in the bottom of the case makes pushing the scent stick out easy as well.
