Yes, cork lined seals can have issues since they are natural. If your concerned make sure to just pull it out and use the food grade silicone lid liner seal.

Cork isn't toxic, it just doesn't taste good.

Our leather is dyed leather and can stain if you decide to wash it under a faucet. DO NOT CLEAN THE FLASK BY HOLDING IT UNDER A FAUCET!! If its dirty use a mild cleanser and mix with water. Then dip a cloth towel in the water, and rub the dirt off the flask. Do NOT apply the soap and water directly onto the leather flask. Always use a cloth for wiping -- paper towels can disintegrate and get stuck in the leather.  Leather is not water proof. You can use a leather waterproofing spray/rub like what is used on leather boots, jackets, purses, etc. if you want to make the leather water resistant. One popular brand is Nikwax.

For those who have received the flask and are wondering about the silicone stoppers.  Cork is a natural product which can absorb flavors and potentially crack over time. The included silicone stoppers are an optional replacement for the cork stopper which comes installed in the lids.  The silicone stopper is longer lasting, absorbs less flavors, and is washable.  If you want to use the silicone stopper, simply pop out the cork stopper and push in the silicone one. If you plan on taking your flask to a high altitude please use silicone stopper. Cork can leak small amounts of whiskey when going from low to high altitude.

They are in a small white plastic bag and can fall behind the foam insert in the box. If you can't find yours, please pull out the foam insert and look behind it.

Unfortunately you probably should not, since glass can shatter under extreme temperatures. The flask is not perfectly symmetrical; it has a higher potential to break.

You should leave enough air in the flask to allow the liquor to expand and contract. Unfortunately glass can break if the lid is on tight and there is no room for the liquor to expand during temperature variations.

Do not fill flask all the way to the top. Allow enough air for the liquor to expand under pressure. If you dont, the glass can break and lids can leak. Do not use cork in the lid for checked baggage. We do not recommend packing flasks in checked luggage because of the extreme pressure variations.

Our flasks were designed in Salt Lake City, Utah. Manufactured In China.
