Amélie Onzon / Woolfspoon (Wolfgang Loeffler)

Unless you've got a set of yesterday's rings (see below), you never know when your nails will need a little repair. Like a good little boy scout, Dutch artist Amélie Onzon is prepared.

Bonus link: if you want to be a bad little boy scout, forget all that rubbing together of sticks. Start a campfire the easy way with this lighter ring by Austria's Woolfspoon (Wolfgang Loeffler).
