I was noodling around on etsy today and found some nice looking Epipen cases. I'm not affiliated with any of these folks - if you've purchased from them, let me know in the comments.
Green Flannel, holds 2 pens, $28.00
Ouch Pouches - lots of fabric selections! holds 2 pens $12.95
Nylon zipper pack, holds 2 pens $18.95
I love Etsy!!!
p.s. here's a link to an Epipen case post I did a few years ago :)
