Please send me a message specifying which earrings you would like to swap out the hardware on, if: - The number of hardware swaps purchased is fewer than the number of earrings purchased e.g - You bought 3 pairs of earrings, but only swapping one. - You have selected more than one type of hardware for your items e.g - You have selected silver & gold / french hooks & ball studs / Clip-ons & huggies. THINGS TO NOTE: ~ All hardware is hypoallergenic. Most is tarnish resistant, but flukes happen. ~ Clip-ons for dangles can sometimes feel a bit tight. ~ Please select the proper clip on variety for your earrings - "stud" to replace your studs, "dangle" to replace dangles ~ Please keep in mind that swapping your huggies out for ball studs will shorten the overall length of the earrings, meaning they will sit higher + closer to the face / earlobe than shown in the try-on photos (if your item originally comes with huggies). ~ The huggies I normally use are 14g. The option in this listing is for a larger, 16g "hoop" to give you more room around your earlobes.
