We recommend 14g 1/2"-5/8" straight barbells for bridge piercings depending on the width of your nose. If you have a new piercing your piercer may size up your barbell to aid in proper, comfortable healing. When your piercing is fully healed you may need to be fit for a smaller barbell length for a secure fit. If you want a dramatic look, 4mm is the largest barbell ball size we offer, it is the perfect way to showcase your gemstones.
