There are two colors: white PP or blue PP. Please take note that the PP wheel color will change gradually because of oxidation reaction. Unlike cheap Chinese PP wheel, this one is hard to break.
We ordered these wheel exclusively as replacement for Thailand's JUMBO and SUMO Hand trucks. The tread is Brown ThermoPlastic Rubber, so they are guaranteed to roll smoothly and quietly. Compare to the default Black PU wheel, TPR wheel may last 2 times longer.
