The mussel corresponds exactly to my expectations and is exactly as I had remembered from my own childhood. She is now with us on the balcony. One half is filled with sand (25 kg from rich, have ordered 50 and only half filled) the other is waiting for warmer weather ;-) All the reviews due to thin material have only made me a little worried, unfounded, as it turned out. Sitting on the edge is not, this is the real not imagined, but now the shell does not fall out of shape or warp. All in all, exactly what I was looking for.
