The oral care product I'm talking about is the interdental toothpick! This is a product I've been using for a really long time. I buy it in bulk to make it last longer, but it also feels sturdier than other toothpicks, so I always buy this one whenever I run out. I didn't really have a specific name for it; I just searched for "interdental toothpick" on Naver and bought it! It's perfect for removing food particles stuck in your mouth after eating, so I'm really satisfied with it. Unlike regular restaurant toothpicks, it seems to remove food particles very effectively! I recommend it.
