Q : i am a little confused' we just found out the hard way my daughter is allergic to nickel her ear is infected' anyway she needs a longer post which one above do i need to pick for a longer post the first choice or the 3rd choice
The standard size for healed piercing is 1/4" (6mm). If you want the longer one, 5/16" would fit most ear piercings. Select the 5/16" from the first option. The 3rd option is only optional if you need an extra post.
