Sorry,i don't know until i mail them?? they weigh aprox 3lbs maybe?? if that?? sorry i can't offer better information,i'll research and get back with you,i know the u.s. postal service used to offer 4.95 flat rate shipping. whatever you can fit in the box for a flat rate,so if they're still doing that???
To be able to fit these in the small flat rate box you would have to take them off the spindle and wrap them up or something to be able to fit them all in the box.
