These vases were created for the Trieste Mini Maker Faire. You can grow in these pots what you want, in PC's cases strawberries, in CRT pots tomato plants or flowers.
As you can see from the photos you can put inside the common flower-pots or you can fill them with soil and plant bulbs, flowers, vegetables, etc.
I don't sell them to abroad costumers (shipment could be very expensive), so Do It Yourself! It's simple and easy. Suggestions: If you fill them with soil use its plastic bag with some holes (plants don't like stagnant water) and expanded clay on the bottom. And use soft soil if you seed.
PC's desktop enclosure are handmade silk-screen printed by Rude Serigrafia (the green one) and Pablo Rizzo (the black one).
