Small display shelf meant to hold 16 1-2 mL perfume samples. The Squiggle design has flat shelves, but is tilted slightly backward to help keep the bottles on the shelves. The Squiggle2 has half inch indentations in the shelves to keep the bottles more stable. They are otherwise identical. They are designed so multiples of the same shelf will have continuous smooth squiggles when set next to each other.
