A lighter case is provided. The lighter case may have a main body forming a clamshell shaped to receive a cigarette lighter. The lighter case may have a grinding apparatus on a portion of the main body or slidable relative to the main body and configured to disaggregate a smoking material. The lighter case may collect the disaggregated smoking material and may guide the disaggregated smoking material into a receptacle such as by scooping or via a piston. In this manner, the smoking material may be prepared.

An electrically powered soap grater and dispenser that automatically dispenses shaved and grated soap into a user's palm. A reciprocating electro-mechanical drive assembly causes a grater plate to reciprocate up and down as it cuts into a stationary bar of soap. A transparent window in the front of the housing lets the user see the soap stored within and shows when the soap needs to be replaced. An optional secondary support stand raises the housing high enough for a user to put his hand under it to receive the shaved soap. Alternately, the main housing can be hung on a wall of a bathroom or shower so that the user can easily place his or her hand under an aperture located in the housing's bottom wall and receive the shaved soap.
