Its material usually has certain wear resistance, corrosion resistance and water resistance.

Wear-resistant materials can prevent the tool kit from being cut or worn in daily use; Corrosion-resistant materials can resist the corrosion of some chemicals and prolong the service life of the tool kit.Waterproof function can prevent tools from being damaged by damp and rain, especially for some electronic tools or rusty metal tools, waterproof protection is particularly important.

Sturdy and durable material: 600D 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. ​

Strong bearing capacity: from size design to material selection, the weight and volume of the tool are considered. The bottom is usually reinforced, such as steel bars and hard plates, to enhance the bearing capacity, and heavy hardware tools and power tools can be placed. Ordinary bags are far less load-bearing than toolkits.
