Got my vacuum sealer from Amazon today

I used mine last winter to make some super-sized cold packs to keep in the freezer.
Mix 1/2 alcohol and 1/2 water in a zip lock baggie - then seal up in the vac bag. Stays squishy but COLD. Great to have on hand around my elderly horse. Molds softly over an aching joint.

I use mine to reclose mylar bags too, like potato chips and stuff that DH gets into
