*by K***R on 16 May 2025*

Binocular eyepieces measure 39 mm. Description says these eye cups are suitable for 39 to 42 mm. The eye cups received are much too large and do not fit. Will be returning. Edit to above. Not only are the size of these eyepieces falsely advertised, the free returns also turns out to be false. I was charged a re-stocking fee when returned. IMO AVOID.
