Collectors and sellers of the insulated tumblers, which were invented by William Stanley Jr. in 1913, suggest that the craze has been fueled by the manufacturer’s marketing strategy, the collaboration with popular companies like Starbucks, the designer colors and a sense that ownership conveys status and exclusivity. Influencers on TikTok and other platforms have contributed to the mania by posting catchy videos of the tumblers.
Collectors and sellers attribute the craze to the limited availability and collaborations with sellers like Starbucks, as well as to viral TikTok videos.
