The flared end looks more like an octopus or squid dorsel and has some nubs to reflect that. The flared in can be inserted in any hole, but the small one is positioned to go into your ass. It's got a great blue color and fits in my whole hand.

The glass is heavy, which is a great thing. It feels so smooth on my skin and cold at first until it got accustomed to my skin. The nodules on the flared end feel especially different inside of me, sticking any part of this inside of any of your holes is going to be a good time. Give yourself time to warm up or enjoy foreplay before either bit, glass does not give, so it's going to feel full very fast. Use lube. Use more, then use more.
Personal Lube

I placed the curved end inside my pointer and index finger, then lowered it to myself and inserted it after I added Lube. Once inserted, it worked like a standard dildo, but angles are important. The shape is really specific, so make sure you're communicating with a partner if you're inserting into a lover.
