About the Caffeine
The Caffeine was an early ilinx Toys yo-yo and predates the 2022 Melatonin, which the maker introduced as its second yo-yo. Contemporary community discussion describes the Caffeine as a stable, limited direct-sale model available through ilinx.
Hollywood Modern Yoyos is the successor identity to ilinx Toys. Surviving sources do not provide dependable dimensions, weight, construction material, response specifications, colorways, or original price, so those details remain unrecorded.
