Reusable pads are easy to store in a pul bag.
Mine have poppers on them to snap around the gusset of my undies and I also use the snaps to fold the used pad in on itself and snap it shut.
At first I was freaked put about whether it should smell but honestly it never does. The weird period smell for me was actually disposable products. I used to smell my period as soon as I went to the loo but with reusable, I could honestly sniff a used pad and not smell anything (I obviously don't! My point is just that periods don't smell, products do. I also find they absorb better and blood doesn't sit on the pad in the same way.)
Sorry for making a massive tangent!
