An application pen includes a hollow pen body made of plastic having a closed end and an open end and an applicator head on the open end of the pen body. The applicator head has a foam, felt or fiber body. The applicator head has an end section that fits into the open end of the pen body. The pen body has mechanical fastening means for positive-locking and/or friction-locking engagement with the outer circumference of the end section of the applicator head without deformation of the end section of the applicator head protruding into the open end of the pen body.
