I use a little pencil purse to hold my little 510 in my purse, I use the pencil pouches to slip the batteries and cartomizers in so they are safe and won't leak out into my purse...but a 510 is much smaller than the ego...so a pencil bag won't help! Try a stand at home and maybe a box of some sort for your purse, sure you could find a quick cheap fix at Walmart or pay for a special one online.
