ive stretched them to a 2g and i havent had any problems with them at all...they all seem to stretch fine with little or minimal pain...well i bought 0g plugs to put in and they dont seem to stretch in my holes at all...maybe theyre not 0's, maybe theyre 00g:dunno: anyone else with plugs this size in their ears, let me know if you had complications getting to zero or not...thanks
