“The edge brush I didn't know i needed. The 'hard' side - i should say firm is really useful at combing/detangling even my 4C edges while the softer side is great at smoothing in product and the end of the brush is the perfect size for scraping the gel out of the pot. And the standd! i never knew i needed it but it keeps the brush clean and clear from hair and the little case the covers the heads too is super useful! One small note, don't press too hard while slicking your edges as the toothbrush heads might pop off and out!”
