Safety First is a simple yet effective design featuring safety pins placed in a manner that they almost create a 3D effect. Did you know safety pins were invented in 1849? And they have served us well over the years. Not only are they used for their actual purpose, they have also been adapted to other uses such as a makeshift fishing hook, lock pick, guitar pick, zipper pullers and body jewellery. Some more adventurous uses include making a chain mail outfit and holding a muffler together!
