### ⭐⭐⭐⭐⭐ Canon binoculars lens covers

Good quality and fit for the canon 12x36 binoculars. A piece of foam stuck on the holding loops to keep them in place has worked for me.

### ⭐⭐⭐⭐⭐ Fits Nikon Prostaff P7 10x30
*by C***4 on 11 March 2026*

Fits my Nikon Prostaff P7 10x30 binoculars perfectly, nice snug fit but not too tight, better than the original lens covers supplied with the binoculars.

### ⭐⭐⭐⭐⭐ good replacement, don't lose again...
*by K***R on 31 March 2026*

straight replacement for original. Make sure to fix it in some way as it'll come off and get lost (again and again). I used some double sized sticky tape.
