I buy all my things from NLS:http://en-nls.com/pict1-38906
Lubricant choice can really change how an onahole feels. I recommend experimenting with different types, but this should be a good standard one:http://en-nls.com/pict1-40767
You can just use soap and water to wash it, but I like to use this specialized cleaner:http://en-nls.com/pict1-27929
And dry it off with a microfiber cloth to keep it lint-free:http://en-nls.com/pict1-39887
Then rub some baby powder on the outside to keep it from getting sticky:http://en-nls.com/pict1-14717
And leave it in a breathable bag to let the insides dry:http://en-nls.com/pict2-5069-9999
You could also get one of these to warm up the insides before use:http://en-nls.com/pict1-38260
Or just let it soak in warm (not hot) water.
