Claim:
A double-ended makeup brush tool having an automatic sealing structure comprising: a barrel shaped in a form of an integrated tubular casing, with a brush hole formed through a conical front end of the barrel so as to allow a retractable ejection of a first brush therethrough, and with an insert hole formed through a rear end of the barrel; a cartridge sealed at opposite ends thereof both by the first brush attached to a front end and by a second brush attached to a rear end, the cartridge being inserted into the barrel such that the cartridge can be axially moved forwards and backwards inside the barrel; and an anti-drying unit interposed between the cartridge and the barrel such that the anti-drying unit can air-tightly seal the brush hole of the barrel in response to axial movement of the cartridge; wherein the barrel is provided with a first locking hole and a second locking hole sequentially formed in the barrel at respective locations spaced apart from each other in an axial direction from the rear end of the barrel, and the cartridge is provided with a locking protrusion protruding from a sidewall of a filter receiving part defined in the rear end of the cartridge such that the locking protrusion can be removably caught by the first locking hole or by the second locking hole.
