What the most sturdy make masturbation toy?

Jadie
So my boyfriend and I are long distance, we get sex toys to play with and work out our energy. He has had two different masturbation cups in the past few months, the first one was some cheap one he broke slowly over time because he was ripping it along the opening, the secend I bought him for Christmas but arrived a couple weeks earlier. Today he sort of popped it. So what would you guys recommend that might last longer
