1.Scenario: Water-based nail polish is water-based. If the bottle opening is left open for extended periods, the water and volatile components will slowly evaporate, causing the nail polish to thicken, clump, or even dry out and become unusable.
2.How the lock/opening mechanism solves this: The locked state is like putting a "sealed cover" on the bottle, greatly reducing the product's contact with air, effectively preventing moisture evaporation and product deterioration, allowing your nail polish to last longer and always maintain a smooth application texture.
