An ABS plastic shell tape measure is a measuring tool that consists of a plastic case made of ABS plastic and a retractable measuring tape made of metal or fiberglass. ABS (Acrylonitrile Butadiene Styrene) is a thermoplastic polymer that is commonly used in the manufacturing of consumer products due to its high impact resistance, durability, and low cost.

The tape measure typically includes markings in both metric and imperial units (centimeters and inches) and can measure lengths up to several meters or feet, depending on the model. The tape measure is usually equipped with a locking mechanism that holds the tape in place at the desired length, and a button or lever that allows the tape to retract back into the plastic case when not in use.

ABS plastic shell tape measures are popular among both professionals and DIY enthusiasts due to their durability, affordability, and ease of use. They are commonly used in construction, woodworking, crafting, and other applications where accurate measurements are essential.
