The ''sleeve filler'', also called ''thumb filler'', is one of the many filling systems experimented at the beginning of '900, in particular it was adopted by [[Holland]] around 1905 and by [[Waterman]] that used it from 1910 to 1915. This loading system is based on the displacement of a ''sleeve'' that wraps the barrel of the pen to hide a large opening made on one side of it. Moving the sleeve, which protects the opening, gives direct access to the pressure bar (on which a relief button was usually mounted at the opening), which can be so pressed using the fingertips.
