Kaleidoscope 'Classic Oil Cell 3-mirror' in Dark Brass by Roy Cohen
Roy Cohen's Classic Oil Kaleidoscope (updated in late 2018 to a 3-mirror system and 1" longer) has several interesting features, including his signature dark brass patina to resemble an antiqued finish popularized by the Victorian, "steam punk" genre, brighter brass accents, and an oil cell filled with brightly colored objects.
Roy has even made the exterior part of the oil cell quite decorative with a bright pattern of green, blue and gold. Its 3-mirror system results in combinations of vivid colors and patterns that are endless.
The kaleidoscope itself measures 6-1/4" long x 1-1/4" in diameter (at the oil cell end). When sitting on its custom base, it is 2" tall. It's gender-neutral, will fit nicely on a desk or table, and is sure to be a hit with anyone on your gift list.
