TETRA is a vase that can be used on its own or combined with other TETRA vases. There are three subtly-coloured versions that can be set in a variety of ways, depending on your mood or the type of flowers you are using.
It occurred to me that it was boring to keep using the same old flower vase, even though the flowers in it kept changing. I wanted to make a vase that you could use in different ways, depending on the type of flowers or your mood. When I saw some concrete tetrapods stacked up near my house, it came to me that a similar design would make an interesting vase.
