Online, I could not find any sources for a brand called "stowaway" or a coat hanger safe called the "stowaway" safe. However, I think I am aware of the product you are looking for. If I am not mistaken, you are searching for a safe which is disguised as a clothes carrier or protector, and is shaped like a square with a coat hanger at the top. The safe is opened and closed using a zip and/or a lock, and can be used to carry valuables, money, passports and, obviously enough, clothes. This kind of safe can be used at home or while traveling, which makes it ideal for all people in all situations. I have found a safe very similar to the one you are looking for, named the Hideaway Hanger. They can be viewed and purchased on this website: http://www.custom-kingdom.com/hideawayhanger1.html. The price listed on this website is $35, although this price does not appear to include postage and packaging.
Your only other option is to try websites where people may be selling their unwanted or unused Hideaway Hangers. You may find such items on websites like eBay and Amazon. You may be able to find second hand coat hanger safes for a cheaper price than listed on the website above. However, there are a number of things you should always clarify before buying a second hand Hideaway Hanger. Ensure that the zip is functioning and works effectively around the whole of the product. Also, if your Hideaway Hanger is also equipped with the lock, ensure that the owner is selling the key in conjunction with the product. Feel free to ask the owner questions about the product's history. You should certainly consider asking about whether the Hideaway Hanger has been tampered with or forcefully opened in any way, as this may affect the quality and security of your potential purchase.
