This is so cute and the perfect puzzle cube for a girl. One of my favorite things about this cube is that there is no stickers to have to deal with. It has heards on it instead of the traditional squares which i found to be a nice little touch and the reasoning for me saying it would be perfect for girls.
Each side has a different color and once the puzzle is all mixed up you need to try to get all of the same colors back on the sides all together, test your skills and see how long it takes you to do so.
This cube also comes with a nice little display stand and looks cool when setting on it. This would make the perfect gift for someone who love to challenge themselves and push themselves to achieve fast timing.
