Abstract: A spare blade storage case for barbers' razors of the type which hold replaceable blades. The spare blades are held laterally in the case which allows the blades to be taken out from the case by a direct upwardly motion. There are provided storage spaces for individual spare blades, each of the storage spaces being defined by a pair of sidewalls which rise from a bottom of the case and are yieldable away from the spare blade as this spare blade is inserted into this space. The sidewalls are provided on their inner surfaces with projections engageable with upper sides of ridges formed on both sides of each spare blade. One end wall of the case is opened so as to expose at least one end portion of the spare blades extending above the ridges thereof.
