Details: The Flex Extender is one of our proudest innovations to date, because it gives you the power to change your System as often as you need to. It’s most often used when you need more of certain products in your routine – think doubling up on conditioner when you’re going on a month-long trip. When you add The Flex Extender to any of your Flex Capsules,* you increase your volume capacity by an additional 1.43oz. It’s most commonly added to The Flex 132 and The Flex 56. *While it’s compatible with The Flex 275, please note that it will be over the TSA limit.
