Purchased 2-3 years ago and used only once. I made an impulse buy, intending to start scuba diving, but never ended up using it, and it became the wrong size. It's a full custom order, made for someone 168cm tall and weighing 62kg, so I recommend it for people with a similar build. The thickness is 4-5mm. Sorry for the vagueness. In the 7th photo, there was a name written on it, so I erased it. There are no tears, and it's in good condition. It's still usable, so please consider it.
