You’ve come to the right place for odd-sized 13mm plugs / gauges. 13mm is technically still labeled at 1/2" inch, but it actually bridges the gap between standard size 1/2" inch and 9/16 inch. Stretching to 13mm first helps to avoid unnecessary damage to your piercing. While this size is usually only popular as an in-between size, UBJ has a respectable jewelry selection to choose from. Both single and double flare variations are available to suit all needs, and materials including stone, glass, wood, silicone and stainless steel ensure you’ll find a pair or piece that’s right for you. Check out our 13mm plugs selection and add to your collection!
