摘要 |
An improved plunger comprises a generally V-shaped handle attached to a top distal end of a shaft. The handle comprises two mirrored arms that face inwards from a base so that neither of them nor the shaft shares a vertical or a horizontal plane. The handle is removably detachable from the plunger so that it can be washed, disinfected, and sanitized. At least one extension shaft portion extends a height of the shaft when it is not collapsed into and housed in the hollow shaft.
