A crayon shaper having a housing which defines an opening for receiving heated air and a channel configured to receive a crayon. The channel is positioned so that the crayon is configured to be heated by the heated air entering the opening. A mold is positioned adjacent the channel and configured to receive portions of the crayon that are melted by the heated air. The housing may have a mold tray configured to retain the mold and detachably engage the housing. The housing may further have a shut-off plate that is biased to a closed position, in which it prevents melted portions of the crayon from entering the mold. The shut-off plate may be movable to an open position when the mold tray is inserted in the housing.

The present disclosure relates to a composition for preparing a thermochromic solid marker, which enables the production of a color development means for a thermochromic writing instrument capable of being erased in response to a change in temperature in the form of a solid marker having desirable physical properties, and a preparation method for a thermochromic solid marker using the same. The composition for preparing a thermochromic solid marker comprises: 10 to 35 wt. % of microcapsule particles comprising a core composition containing a leuco dye and a developer, and a polymer resin shell surrounding the core composition; 5 to 20 wt. % of a gelling agent; 30 to 60 wt. % of water; and 0 to 10 wt. % of a glycol-based organic solvent.
