API 550B Discrete 4 Band EQ for 500 SeriesBased on the API 550 EQ from the late '60s the 550b is an update to the classic EQ that played a major role in the history of music recording but adds an additional filter band and several new frequencies. Incorporating API's exclusive circuitry and proprietary components (such as the legendary API 2520 Op Amp), the 550b artfully blends the past with the present. So many hit records still depend on the unique 550 sound that engineers around the world

Poor quality control… Received a used pair
Size: 12, Color: Birch Beige/Farro/Ivory, Size: 12, Color: Birch Beige/Farro/Ivory
The shoes that were delivered showed signs of wear. Not sure if this was a used pair or a display pair but this should have been caught from the beginning. I would normally return them, but will be out of the country for the next month and don’t have the time. Unacceptable quality control from the official cole haan store front.

Poor footbed but otherwise good.
Size: 10, Color: British Tan/Dark Chocolate/Natural
Comfortable. Replaced mediocre footbed that has no arch support with something else and it is now great. True to size.

Best autograph pens I've found!
Color: Multicolor, Size: 1 Count (Pack of 4), Style: Fine
I love these pens! They come in a nice hard case so no worry when throwing them in a backpack. Perfect for autographs, they dry extremely quick and are very brilliant colors.
