New Type Automatic Pencil_ Revealing Society

When adding new lead to an automatic pencil, if your hands are unsteady and you lack patience, you might even get frustrated due to repeated failures. This new type of automatic pencil is specially equipped with a spiral device. You just need to insert the lead in the direction of this "whirlpool". There is also a vertical channel at the bottom of the whirlpool to ensure that the lead can enter the pencil core vertically, guaranteeing the normal use of the pencil.
