Colmena is a local exchange for families in Barcelona. Bundle what your kids no longer wear or use, earn credits, spend them on bundles from other families. No money changes hands.
How it works
Clothes, shoes, gear, toys, books. Group by age range and category, add a few photos, and submit.
Your first approved bundle earns you starter credits. Every exchange after that earns more.
Browse by age range and category. Reserve a bundle with your credits.
Coordinate a quick local pickup with the other family.
Every bundle is reviewed by a person before it goes live.
Access is approved. This isn't an open marketplace.
Report or block if something feels off.
When an exchange doesn't go well, a real person helps sort it out.
List a bundle, get credits, find what they need next.
