أغطية عدسة شيئية مطاطية من Opticron لقطر خارجي 33mm

I was worried about losing lens caps in the field, but these rubber covers snap on tight and haven't budged once. The 33mm fit is perfect for my binoculars, and they feel durable enough to handle regular use.

The rubber is firm enough to stay put but pliable enough to pop on and off without any fuss. I was expecting these to feel flimsy, but they seat perfectly over the 33mm objective tubes and have survived a few drops already.

The rubber is surprisingly firm yet pliable, so the 33mm covers twist on snugly over the lens tubes without any annoying wobble. They've stayed put through a few damp hikes, which is exactly the reliable protection I was hoping for.
