PURPOSE: A chalk case is provided to fix a thin paper at the lower part of the chalk and form cutting lines at the lower part of the paper, thereby preventing staining of chalks when users take out the chalks from the chalk case. CONSTITUTION: A chalk case comprises a chalk body(10) and a paper. The paper covers a chalk. The paper comprises a cutting line(20) which is formed at a location having some distance from the bottom of the chalk body. The paper can be easily separated from the chalk body by using the cutting line. The bottom part of the paper which covers the chalk is fixed on a case bottom(30). |
