Protective tool Prevent collision and friction: The material of tool kit generally has certain cushioning performance, which can effectively avoid collision and friction between tools, prevent the surface of tools from scratching, damaging or dulling, and prolong the service life of tools.

Resist external factors: some toolkits are made of waterproof, dustproof and moisture-proof materials, which can protect tools from external factors such as rain, dust and moisture, especially for tools that are easy to rust or are afraid of moisture, such as metal tools and electronic tools.

Professional storage design: there are many partitions and compartments inside, which are scientifically arranged according to the types, sizes and shapes of tools. For example, long wrenches and screwdrivers have special long slots, while small screws and nuts have corresponding small pockets, so as to avoid tools from colliding with each other and find the needed tools conveniently and quickly. However, the internal structure of ordinary bags is relatively simple and lacks such fine division. ​

Sturdy and durable material: 900D waterproof Oxford cloth, and some toolkits used in special industries will also use special fabrics such as antistatic and environmental protection. Compared with the light cloth commonly used in ordinary bags, the tool kit can withstand the weight of the tool and the puncture of sharp corners, and its waterproof performance can also ensure that the tool is not affected in wet environment.
