Underarm hair removal recommendations

Hello! Summer is already here ㅠㅠㅠ It's so hot and humid, and it's making me feel down, so I think I'm craving revealing clothes even more??? Currently, I have my underarms and Brazilian waxed via sugaring, but I wanted to recommend an underarm product. Actually, it's my boyfriend's razor blade, but for me, it's for underarms lol... It's a secret... The blade was really good; I didn't get any cuts, so I recommend it.
