ZerustRust Prevention Multipurpose Poly Bag with Zip Closure with Corrosion Prevention and Protection - 6" x 8"- Pack of 20 - Made in the USA

Excellent to have around in the shop. I put some moulds in them that I would prefer not to oil for storage, and not a freckle of rust has appeared. I just squeeze the air out and zip it shut with a rust preventive chip in it too.

Keeps my cell phone dry when it pours.
