one of a kind (ish)
Some are samples, some are made from experimental or test fabrics. Or maybe there will be some very last pieces of a limited shade. We don't want to waste anything, and how cool is it to have something no-one* else has? If you love something it's best to snap it up because there's no guarantee it can or will be repeated! One of a kind (ish) items are made in our most popular sizes.
*no-one ish. We might have more than one size or style available, but not many.
