• CONVERTIBLE DESIGN - The stainless steel container doubles as 2 insulated drinking tumblers for you to pour your favorite drinks and cocktails directly into. We've even included 2 oz integrated pour lines to help you measure cocktails and proper pours. No need for extra glassware or cups!
• WIDE MOUTH & NECK - Each 500 ml glass decanter is hand blown with a wide mouth and neck to make filling and pouring alcohol easy, quick and convenient. The mouth is wide enough to drop ice cubes directly into the decanter for ready made cocktails, sangria or chilled wines and liquors.
• LIGHTWEIGHT & PORTABLE - Our expert design team has perfectly balanced structural durability with a lightweight design. All the glass, steel and silicone combine to a total weight of 1.7 pounds which is comparable to the weight of most double insulated thermos bottles and drinkware containers.

User questions & answers

Question:	Has anyone tried this with hot liquids
Answer:	I have not.
Question:	Can any or all of these components be cleaned in the dishwasher
Answer:	I put all in dishwasher- except stopper. I hand wash that to be safe so as not compromise the sealing ability. Love this product so much!!
Question:	I've been reading reviews on the original kickstarter page regarding the stopper leaking. Has this issue been resolved
Answer:	The two that I have from Kickstarter don't leak, but obviously some are as the company had an update for backers explaining what happened - essentially an issue during manufacturing. They've identified the problem and do have a fix in place, folks who have ones that leak can contact them to get a new stopper or instructions on how to fix their own. If you got one from Kickstarter, check the updates.
Question:	So many mentions of leaking but no explanation of the cause, even though I can see the glaring design flaw just in pics. What was the actual fix
Answer:	The product does not leak. There was some QA issues with our stopper in our first batch of product shipped between Nov 2019 and Feb 2020 (3 months). Additionally you'll notice many of the comments are not verified purchases from amazon. Lastly, any product that had any issues was remedied free of charge. We stand behind our product. Cheers

User questions & answers

Answer:	Hello, Miguel from Tall Ridge here! This mug does include a press-in lid. I hope you find this helpful!
Question:	What does the top of the lid look like? I'd like to know what the "sipping hole" looks like. Can someone post a photo
Answer:	Hi SandyLynn - Wendy from Tall Ridge here - Thank you for your inquiry! The Coffee Press In Lid is similar to the Tumbler Press In Lid located here https://www.amazon.com/Hydro-Flask-Honeycomb-Insulated-Tumbler/dp/B01N9SQQMD I hope that is helpful!

• Measures: 9” H x 4”W "

User questions & answers

Question:	I am aslo confused by the picture. It looks like a set of 4 all with different sizes and model numbers underneath....what are the 4 different sizes
Answer:	What you are ordering are a set of 4 different sizes - read the description. On down, you will see “frequently ordered together”. If you just want one, order the 16 oz. like we did. It is great. It doesn’t leak and travels really well. We ordered a couple so we could travel with more.
Question:	can i buy just the white plastic cap for the flask under the chrome cap
Answer:	I don't have a helpful answer here. The cap that seals the flask is not available separately. However, check your local grocery store, Kmart, Walmart, etc. for a less expensive version of the flask, and the cap is almost guaranteed to fit (same manufacturer for many of these products).
Question:	Is the top real chrome or plastic chrome? Can it pass a metal detector at the ballpark
Answer:	It has a plastic call underneath the chrome cap. If you use just the plastic cap you will be fine with a metal detector.
Question:	Are these 9" X 4" round or are they 4" wide X 9" tall X " ? " thick
Answer:	This item is not round. It has a flat back and rounded front. So, I would say they are more 4" wide x 9" tall. I do know that it will hold 26 oz total. Hope that helps.

User questions & answers

Question:	what is this made out of
Answer:	Our product is a four-layer lamination that is somewhat proprietary but is BPA-Free and the ink in built between the 3rd and 4th layers so it can not migrate through the inside or outside layers. The four layers make it far stronger than other flexibles in the market :)
Question:	Can you put it in the freezer
Answer:	I didn't put mine in the freezer but if you left space for the liquid to expand I don't see why you couldn't. I would experiment with just one in case there were any issues.
Question:	How hard are these to clean
Answer:	Just as easy as any other flask to clean.
Question:	What size is the opening, ie, what size funnel spout will work
Answer:	The diameter of the opening is a little bigger than 3/8” of an inch or about 11mm. Pretty much all kitchen funnels work great! I recommend holding a funnel just a little over fully seated on the flask as it seems to improve liquid flow into it :)

Question:	What’s the difference between this one and the hydro flask 16 oz travel coffee flask | stainless steel & vacuum insulated
