"Small. Doesn't take up space. Easy to use." Functional items in the palm of your hand. Matador's mission is to design the world's most user-friendly, portable adventure items. Items designed with excellent cutting techniques and construction technology are useful in situations such as travel, adventure, and the outdoors. Matador's Betalock is a carabiner with a key. You can quickly attach items together and lock them with the key to protect your important belongings from theft. It is a TSA lock. It is even more convenient when used with the separately sold Betalock accessory cable. A TSA lock is a lock approved and accepted by the Transportation Security Administration (TSA) of the United States. It allows you to check your luggage with the lock on, even in the United States, where security checks are the strictest.
