Possibly going to try my hand at extracting skunk essence this year. My question is, how to store it/ who to sell it to?

I just leave mine in a glass jar in the garage. Tip....don't put the jar on a shelf where you can knock it over and break the jar, leave it down low somewhere and/or don't use glass. Ask me how I know.

Use glass as it will eat plastic in it's pure form with prolonged direct contact and a metal lid if shipping or contact with the pure quill is possible. My bottle of choice is a 4oz Boston round bottle with a paper or foil lined lid as unprotected lid will corrode over time.

Keep in mind it stinks and you will stink so that needs a plan in place to keep that from hampering your social life at work and at home.

I have some small glass IV bottles with the rubber top.

Store it in an empty liquor bottle. Lure makers usually buy it. I know a guy who buys it in New Jersey. You could contact some lure makers and ask how they like it bottled and shipped.

Store in glass bottles. Put the bottles in a plastic bucket. Pour kitty litter around the bottles and pop the lid on it. I have some stored like this in the shed. If someone walked into the shed, they wouldn't know it is in there.

Add others stated use glass with lined lids.
I store bottles of skunk juice in ammo cans

Store in small glass bottles, Wax the cap and top of bottle.Best place to store is in one of those green metal ammo cans. Keep in cool place, but not in the house.

I like to cut out the pods ( glands?) and store whole.

Way less stinky. When you need some just grab a pod and extract all or some. If selling just gather up a few quart jars and extract it all at once.

Less smell and essence stays fresher.
