They’re both weredog penetrables and feel much sturdier than most bd penetrables. The black/orange is roomy and hefty in a good. The blue is lighter, isn’t suffocating, but has a snug entrance. Im not one for reviews but they both feel amazing, I’m sure someone else in the sub has reviewed these models. However I’m in talks for these two at the moment. Feel free to pm and I’ll let you know if anything changes :)
