Originally a gift for my girlfriend, this test tube spice rack was designed with the end user in mind.

The test tubes give it a unique look so it works as functional decor. With self centering geometry, the test tubes fall naturally into place and are secure yet very easy to remove.  Laser cut as a stainless steel piece with just two bends and two holes, it costs just $6 each to produce at a quantity of 50.  I have been giving these out as gifts and plan to start selling them.
