LOL that's what I had actually bought them for was to size up from a 0 to the 00 because I actually bought some hello kitty ones that where 00 and I thought those would be the best way for me to size up on my own but come to find out I was able to slip the hello kitty ones right in ,so had no need for these.
Yeah I like their look too but sadly it's to much trouble for me to wear them on a daily basis because I have really long hair and it always gets tangled around them lol
:) ,that's how I did mine I went from a Normal ear piercing to a 14g then 8g then 6g the 2g then 0g and now I'm at a 00g and that's where I plan on stopping ,I sized up all but the first time on my own cause I have a habit of pulling on my earrings and stretching them on their own, Also if you find a nice heavy metal pair that you like get those and wear them it will help stretch slowly with out pain also.
I went straight from a 14g to a 2g. Haha that was painful but fun.. the biggest I went was a 7/16.. now my ear won't close smaller than a 4 because I didnt clean stretch them.
Yeah jumping sizes can be painful one my good friends went from nothing (no ear piercing at all) to a size 0 he said it hurt like hell but he took it like a champ .Well the bigger you go it's always going to make it difficult for them to shrink back to a normal size that's why I have no plans of going any bigger.
