I always return home to see a mountain of shoes piled up and that really made me want to own a special area to keep these shoes. However, it is not possible to store them without damaging them by piling it up. Hence, there is no way I can keep them without spoiling it. 
Whenever this happens, I think about those slippers that does not require much care but consumes plenty of space. How these slip­per an actually give me more storage spaces for my shoes so that I can prevent my shoes from damaging. Eventually, it led me to thinking about the mosquito coils we use back at home during summer time. 
When I was a child, I think that the shape and the joint of the mos­quito coil is very interesting. By taking the shape and joint of the mosquito coil, I will be able to change the structure and principle of it then applying it to my design to make storage of slippers more convenient.
