Plastic Hooked Weights, Set of 25 Masses
by GSC International

This set of plastic weights comes in a convenient plastic case for easy transportation and storage of the weights. The set includes 5g, 2g and 1g hooked masses. Each one features a slot in the bottom, and a small metal bar running between the sides of the slot. This slot and bar design allows for the hooked masses to be connected together in any combination required, as the slots in each mass are big enough to accommodate the other sizes.

Each weight is made out of a durable plastic, and have their weight clearly listed on the side. There are five 5g weights, and ten of both the 2g and 1g weights. This gives the weight set a total mass of 45g to be distributed over the course of an experiment. Its rugged and durable construction makes this weight set ideal for use within a classroom setting.
