HealthyHey Nutrition High Absorption Magnesium Glycinate 550mg | 300 Capsules | Muscle | Sleep

The lid with a press-type design is quite loose. It tends to shake, and there's a risk of air entering and potentially spoiling the capsules. The manufacturer should consider redesigning the lid to make it tight and secure. Since I received the product today, I cannot comment on the effectiveness of the magnesium capsules yet. It's somewhat surprising that a manufacturer who has designed the box and outer carton so well has overlooked such an important aspect of the product's packaging.
