On a sidewalk, an unassuming junction box sits strapped to a fence. Inside, dozens of keychains, stickers, mini figurines, and other novelties wait to be discovered by eagle-eyed passersby or trinket traders who have traveled across the city to exchange their treasure.
Trinket trading has taken off on social media in recent weeks. The trend first originated in Philadelphia, where Philly’s Trinket Trove began documenting the contents of a repurposed junction box on TikTok in September of last year.
It has since spread nationwide, with communities from New York to San Francisco setting up their own boxes of assorted knick-knacks for anyone to stop by and trade. The only rule: “Give a trinket, take a trinket.”
TikTok creators across the platform have jumped on the trend with enthusiasm, documenting what they find and what they leave behind in vlog-style videos. Others are announcing new trinket box locations, inviting neighbors and fellow social media users to spread the word and join the fun.
While the trinket boxes are primarily aimed at children, trinkets themselves are having a moment globally. Since hitting the market in 2019, Labubus have become a global phenomenon, sparking a viral craze for the palm-sized monster dolls in 2025. Smiskis and Sonny Angels, both cutesy figurines, have also had their own viral moments as blind boxes continue to populate social feeds. Even Michaels and Walmart have begun carrying their own mystery boxes to capitalize on the trend.
In much the same way, the trinket box trend offers a wholesome moment of surprise. Instead of encouraging people to purchase something new, it promotes the more sustainable idea that one person’s trash is another person’s treasure.
Like little free libraries or geocaches before them, trinket boxes lean into whimsy and analog activities, two trends forecasted for 2026 as antidotes to brainrot and digital fatigue.
Across social media, one of the biggest trends right now is being offline. Analog bags, snail mail and grandma hobbies have all been trending in recent months. The hashtag #AnalogLife is up 330% this year, according to TikTok data shared with Axios, and “analog wellness” was named a top trend for 2025 by the Global Wellness Summit.
Parents have long expressed concern about the iPad generation and the impact of growing up glued to screens and reliant on technology for perpetual distraction. Here, something as simple as a trinket could offer a small moment of respite in an increasingly saturated technological world. Just make sure to leave something behind for the next person.
