Upgrade any earring (unless a stud specific earring) to have ultra hypoallergenic Titanium hooks, instead of the traditional hypoallergenic/nickle free hook or stud. Simply add this upgrade and to the same qty of earrings you want swapped.
Example: You purchase 2 pairs of earrings, you should add 2 Titanium upgrades. If you are wanting only 1 of the 2 upgraded, please leave notes to which pair you are wanting upgraded.
