I've taken down many items from MP.
They're at the in-world store.

18+ Adult items are listed here:
https://marketplace.secondlife.com/stores/174199
(in-world 18+: http://maps.secondlife.com/secondlife/Neo%20Star/57/210/3501)

The main shop location is in-world.
If the shop is down, the alternative is Marketplace, Audax shop in Utilizator sim, or Club Hatsune sim.

Note:
I recommend shopping at an in-world store instead, as it is more reliable and there are many more things that I only sell in the mainstore, including freebies.

PLEASE READ THE ITEM DESCRIPTIONS!
If you have problems, TRY TO CONTACT ME before leaving a hostile review.
Offline IMs are SENT TO MY EMAIL, and I have never received contact from people who leave negative reviews saying the things don't work due to their own computer/viewer's technical problems that are EASILY SOLVED.

Will refund ONLY for duplicate purchase.
