Don't pay retail for cheap, plastic, generic binoviewers w/o eyepieces when you can get these for around the same price or less.
Both binos and Parks 31mm Plossl eyepieces in excellent lightly-used condition. Smudges, dust, and other signs of normal use.
German-made with awesome, solid build quality and retro look. Rotatable compression rings to hold the eyepieces.
Work great.
Only selling because I upgraded.
