Overview & background
A nail polish wall in a store is a sea of small bottles, so brands look for ways to stand out, and molding a diamond or faceted pattern into the glass is an effective, low-cost one. The relief catches light and sparkles next to the polish color, hints at glamour, and gives the small bottle extra grip.
Because the pattern is in the glass, it differentiates the bottle on shelf without adding a decoration step, and it survives the whole life of the product.
