Zipper bags

These bags come in sets of 100 units and are perfect for keeping needles and other small objects. You can use them, for example, to store the jewelry you're not using and small pieces to protect them from dust and dirt. If you store them in a zipper bag, the pieces won't get lost or tarnish. 

If you're a professional piercer, these bags are also perfect for putting the jewelry you sell to your clients. To sum up, they're ideal for everything, even to store mayo, if you want to.
