Khloe Kardashian celebrated her 31st birthday this weekend, and making the day even sweeter were the gifts she received from her nieces, North West and Penelope Disick.

There’s nothing quite like handmade gifts, and those made by children are even more special. They put so much of themselves into their handiwork that it’s hard not to cherish them forever.

Kim Kardashian and Kanye West’s daughter North spelled out her Aunt Khloe’s nickname–KoKo–with pom poms, glitter, and construction paper. Kourtney Kardashian and Scott Disick’s daughter Penelope wrote ‘KoKo LoKo’ with crayons and glued feathers to her masterpiece.

Khloe Kardashian received many birthday wishes via social media in addition to the sweet gifts made by her nieces.
