Despite its delicate aspect, the sculpture is actually quite strong. It is made from a flexible polyamide so although it feels hard, this flexibility allows the material to absorb the impact of a fall. The material is not brittle so it doesn't shatter on impact. We have dropped the sculptures dozens of times (mostly by accident) and, so far, not even the teeth have broken. For a sculpture, it is very resistant and durable.
The wall version can be hung from a hook or nail directly between the spaces formed by the pattern of the mesh. You should handle the sculpture with care when doing this, just as you would when hanging a painting. Again, the structure of the sculpture is quite strong and very light so you can hang the sculpture up for years without any risk of damage to the sculpture itself or the wall it is hanging on.
You'll need to pledge first and then, once the project reaches its deadline, you'll receive a questionnaire where you'll be able to specify the colour that you want, alongside other details such as your shipping address.
