Lightning toothbrush

When using straight shank toothbrush, toothpaste foam will flow from toothbrush handle to hand easily. However, the twist design between front handle and grab handle will change the flows in avoiding foams to hand. Meanwhile, it is great to make use of groove design between twist and grab handle that you can place the toothbrush cleanly on the table.
