Quivers are not small problems. You need to choose the quiver that is best for you. For example, if your arm is short and the arrows you use are long, back quiver may not be a good choice for you. If you are going horse archery, or want to practice shooting when moving, then a manchu or korean quiver may be a good choice.
Currently the shipping cost is calculated on the package size (length x width x thickness) as well as the package weight. Therefore a regular quiver, if ordered with bow and arrows may increase the package thickness, resulting in very high shipping cost.
