These are the 3-D printed flower vases made specifically for attaching to you bicycle designed and sold by Colleen Jordan of Etsy store Wearable Planter. They are an extension of her preexisting wearable planter jewelry line we posted last year. The planters attach to your bike’s frame or handlebars using an integrated plastic clasp or elastic strap. And the best part about a planter on your bicycle is you’ll never run out of plants to put in it! You see plants everywhere outside when you’re biking!
