As a result of inspiration from my... uh... , well, he's, ah..... hell, from this-guy-I-know who had custom silicone bands made for his "group," we now have NWI silicone bands (size M) for sale for $2 each. They are light blue, they glow in the dark (oooo!), and they say "NWI Chinchillas" on them. They are for purchase in the webstore. Pic below. They look much better in real life -- it's actually really difficult to get a pic of the wording without the flash completely erasing it or the band ending up completely blurry.
