Tin and cover very good and solid, dimensionally stable. Would also hold if one takes her time in the pocket for a trip. Because probably many, like myself, compare multiple products and superior which it should be now: These here are better than those with the blue cover by far. You know what I mean :-) I ordered both products at the same time, this one made me just more confident. Unfortunately, there is this one of MAM my knowledge, only in this one size. The only disadvantage. If someone wants to have even more at home in the range, then you have to resort to other brands.
