Product took 3 months to arrive! but it arrived in good condition. The beads are smooth and the rods provide just enough resistance so that the beads don’t slide around accidentally. The bottom of the abacus has no rubber stoppers though so it needs to be placed on top of something rough to prevent it from moving when using.
