Plastic eyepiece boxes (D=80 mm / V=120-200 mm)

Durable plastic eyepiece storage cylinders are essential for eyepieces to protect sensitive optics from dust, dew and other mechanical damage. The top and bottom of the cylinder can be unscrewed and adjusted to the height of the eyepiece, barlow, while also protecting the optics from shocks.

D stands for the inside diameter, M for the height and its range from t to t in mm.
