Tiny boxes.
Big sidewalk joy.
All over the world, neighbors are bolting little swap boxes to fences and storefronts. Drop a small treasure, take one home. This is the map that helps you find them, build them, and look after them.
A trinket trade box is a tiny public swap shop.
Picture a weatherproof box mounted at kid-height on a fence or a shop window. Inside: buttons, toy cars, seashells, stickers, pressed pennies, little drawings. The deal is simple. If you take something, you leave something you would be excited to find yourself.
It grew out of the Sidewalk Joy movement, started in Portland, Oregon, and now spans thousands of boxes across the globe, tagged #sidewalkjoy.

“Only leave an item if you would be genuinely excited to find it yourself.”
Three ways to play
Leave a trinket
Bring something small and delightful. Roughly a fair, one-for-one swap, usually under a couple of dollars.
Take a trinket
Found a treasure that makes you smile? It's yours. That's the whole point of the box.
Look but don't take
No trade on you today? Totally fine. Browse, snap a photo, and come back another day.
The whole family of sidewalk joy
The movement started in Portland, Oregon in 2022, when artist Rachael Harms Mahlandt built a tiny dinosaur diorama on her block and began mapping the little wonders popping up around her city. That grew into the Worldwide Sidewalk Joy map, a global guide to thousands of these spots, tagged #sidewalkjoy.
That map includes trinket trade boxes like the ones you'll find here, plus a whole family of other tiny public installations neighbors build for each other. We focus on trinket swaps. Here is the rest of the family you might spot out there:
Trinket trade boxes
Take a small treasure, leave one back: buttons, toy cars, shells, stickers, tiny wonders. This is our corner of the map.
Free Little Art Galleries
Pint-sized galleries where you take or leave tiny original artwork. No admission, no velvet rope.
Little libraries & book nooks
Take a book, leave a book. The original sidewalk-sharing idea that inspired the rest.
Seed libraries & swaps
Free seeds, bulbs, and cuttings shared so a whole block can grow something together.
Toy swaps
Like trinket boxes built for littler hands. Trade one small toy for another.
Puzzle exchanges
Borrow a jigsaw or brain teaser, return it when you're done, and grab the next one.
Pocket cinemas
Tiny weatherproof boxes with peep-show film clips and View-Master reels. Pure whimsy.
Curiosities
Duck exchanges, rock gardens, joke stands, and the one-of-a-kind oddities neighbors dream up.
