It is actually well made and of good quality, comes without any instructions. So yeah, making it pop is quite easy but be carefull since it pops a bit differently situationally. Meaning it will not always expand in both directions depending how you grab hold on it. It might also only expand to the bottom side and well if you aim badly you might take a poke at your family organisation central if you catch the drift. And locking it back into the primal stage is kinda tricky. After you done it a few times tho it gets easy. Press it together by pressing it against a solid object and slightly give it a soft turn while doing that. Do not grab it at the sides while doing so, or you get cut by the metall.
