It would be great if NLS stocked those!
You could always try this:https://boards.onahole.eu/a/res/198.html
Personally, I use this spray:http://en-nls.com/pict1-41683
and this cloth (includes 2!):http://en-nls.com/pict1-39887
because they're both from companies known for making quality products.
For the inside you could also just use your fingers to remove excess moisture and then leave it overnight in a breathable bag:http://en-nls.com/pict2-5069-9999
If you use an antibacterial soap then you probably don't need the spray anyway, but I use this stuff:http://en-nls.com/pict1-27929
One bottle of this concentrated onahole washing powder lasts a VERY long time!
