Sweet banana scent with lasting hydration
Flavor Name: Banana Cream, Size: 0.15 Ounce (Pack of 1), Flavor Name: Banana Cream, Size: 0.15 Ounce (Pack of 1)
Sun Bum Cocobalm in Banana Cream smells and tastes like a tropical treat, making it fun to apply often throughout the day. The coconut oil and aloe vera formula keeps lips soft and moisturized without feeling sticky or greasy. It’s perfect for daily use at the beach or just combating dry Florida air, and the subtle flavor encourages reapplication. Great quality from a trusted sun care brand.

I can’t stop buying these.
Flavor Name: Banana Cream, Size: 0.15 Ounce (Pack of 1)
This is my favorite lip balm. It’s thicker, but doesn’t feel too heavy. It’s super hydrating and does not come off as soon as you lick your lips!
