Do you love your Farpoint Astro SBIG Desiccant Plug? Then when it's time for a refill, you need the genuine part. Just keep in mind this is only the refill pack, and not the plug itself! You remove the plug and discard its desiccant pack. Then you simply fold the refill package and insert it into the existing plug, then install the plug into the SBIG camera again. No need to bake out the desiccant plug. Product contains ten (10) packs.
