Retractable pen cap

During our study, we are always troubled by short-pencil, for it makes our writing difficult. This phenomenon makes a great waste.
Here, we make a elastic cap on the end of the pencil, so that the length of the pencil can be changed according to our need. The notch in the cap can meet different diameters of pencils. Besides, we can compress the cap and set in the pencil lead, which can protect our pencil well.
