There is some rust where the ring joins on. The ring is unable to be unscrewed from the main part.
I ordered the black large plug (not very large if you are experienced in anal). Quality is excellent! Very smooth and gets very nice and slippery with silicon lube. It feels slippery even when i wash it with liquid soap, so careful not to drop it. The packaging was very safe. The plug was wrapped in a piece of foam and then put inside a drawstring velvet pouch! You can use the same packaging to store the product safely so that it never gets scratched. The description of the envelope was very discreet. It said "Lock parts". Even if someone touches the envelope, they won't know what's inside. Item was delivered to Greece in 71 days. It traveled from China to Sweden with cargo train, then to Greece by airplane. Carrier was with AliExpress Standard Shipping (handled by Yanwen / PostNord / ELTA). Seller was kind to extend buyer protection due to corona virus delays. The website doesn't allow me to upload photos at the moment, if the issue is fixed i will post photos as additional feedback.
Tested for the 1st time... while i was having an orgasm, the contractions pulled the base into my ass. The diameter should be wider... that is a major problem with most plugs that do not have a T-shaped base. Thankfully i was able to hold it by the ring and pull it out immediately. So play safe, maybe even tie a shoelace at the ring for more protection. And of course i would suggest anyone sleeping while weaaring it.
