That's right... I have just sold my 1000th Opti-Dry Unit to an Astromart user. These have been VERY popular.
Opti-Dry is a self-contained moisture protection device. These great devices are designed to absorb excess moisture such as dew that may form on any of your equipment, EP's, telescopes, or other valuable equipment. You place them inside your eyepiece box, inside you corrector or refractor covers, inside scope cases, or inside any equipment boxes where you want to make sure moisture doesn't get to you stuff. Moisture left unchecked can wreck havoc on optics, metal and delicate surfaces.
Our Opit-Dry are NEW and IMPROVED. Now Opti-Dry come with a "BLUE" indicator packet and a whopping 5 grams of desiccant. What is a blue indicator pack? This blue packet will turn pink when the desiccant has absorb all the moisture it can hold and it is time to change with your FREE replacement pack already included.
Don't take a chance. Use Opti-Dry for peace of mind.
