This is a dart case made of EVA material.
The interior is made of soft material that gently protects the darts.
In addition, there is a rubber strap on the dart holder, so you dont have to worry about the barrel falling out in the case.
The flight is just the right thickness that will not break or bend.
There are also two pockets with a zipper compartment, which can be used to store the saree and spare tips.
