ABS resin is an abbreviation for acrylonitrile butadiene styrene, a mixture of three materials. The advantages of ABS resin include its high density, which makes it resistant to surface scratches. ABS resin is a strong material with excellent impact resistance. It is also a popular material for suitcases. ABS resin also has the advantage of being relatively aesthetically pleasing and highly impact-resistant. The casters use "silent casters" that significantly reduce the perceived volume of noise. Furthermore, the "double caster" system allows for smooth, gliding movement, providing quietness and easy maneuverability. The lock is a dial-type lock that can be set to your favorite number.
