Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
I was actually quite pleasantly surprised by these stickers! Lots of variety - flowers, bows, butterflies, hearts, even flamingos! - and lots of different colours. They're easy to apply and good adherence to the nail. Excellent value for money!
