Hey I use them! I really like them because they are reusable.. it weirded me out at first but after going through it... I realized it just get dirty then you clean it

you could try etsy or something - some people make them there. I've been wanting to try making it myself but havne't gotten to it yet.

when I was shopping for them I found some places on etsy had home-made ones for decent prices so that's what I tried.
