  We revisit low-scale gauge mediation models in light of recent observations
of CMB Lensing and Cosmic Shear which put a severe upper limit on the gravitino
mass, $m_{3/2} \lesssim 4.7$eV. With such a stringent constraint, many models
of low-scale gauge mediation are excluded when the squark masses are required
to be rather large to explain the observed Higgs boson mass. In this note, we
discuss a type of low-scale gauge mediation models which satisfy both the
observed Higgs boson mass and the upper limit on the gravitino mass. We also
show that the gravitino mass cannot be smaller than about 1eV even in such
models, which may be tested in future observations of 21 cm line fluctuations.
