A replacement lens cap for binoculars (or anything similar which takes a simple covering cap).

Use the green “Customize” button to change the internal diameter and internal depth to suit your own particular application.

Features

• Reinforcement rings at corner and opening. These also help to grip the cap when putting on and taking off.
• Slight taper inside, to make it easier to get cap on and off.
• Ring for attaching a thin cord so the cap doesn't get lost.
• Hidden air hole to let air out (in) when putting the cap on (or taking it off). Listen for the whoosh!
