The materials used to make the tool kit are generally tough, the stitches are firm, and the quality of hardware fittings is reliable, which can bear a certain weight of tools without deformation or damage.
For example, a high-quality tool kit will be made of high-strength nylon or canvas with metal zippers and fasteners to ensure that there will be no problems such as zipper breakage and fastener breakage during long-term use.

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 is used, 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.
