I have had skins in my fridge for 2 years now and still good . Need to add water to the salt every so often to keep it wet or they will dry out and be ruined. Make sure they are covered with the wet salt or any area that is not covered will also dry out. P.

I bought a dozen from a tackle dealer in RI years ago. They were dried. I still have a couple left. The amazing thing is that I would use them. Leave them on the plug to dry and the next time I used them they were good as new after about 5 minutes in the water.
