I have three different sizes of these plugs in gradual order up to 2 inch and am considering sizing up in the future. These are quality and solid pieces and are super easy to clean after use. In use, they feel every bit as solid inside as out and there is no give or squish. I personally feel like this makes insertion easier, but still follow the rules, plenty of lube and go slow. If you want some quality plugs that you’ll likely never need to replace, these are it, and the variety of sizes gives you plenty of options. If you’re considering purchasing these, just do it.
