Actress Kim Ji Won has surprised fans with an unusual personal habit, revealing that she carries two toothbrushes and two different kinds of toothpaste wherever she goes.

On October 23, her agency, HighZium Studio, released a video on its official YouTube channel featuring the actress introducing the essential items she brings with her during filming.

Among her everyday belongings, Kim Ji Won showed off a dental care kit containing two toothbrushes, two toothpastes, a tongue cleaner, and dental floss.

The actress explained that keeping her teeth clean is an important part of her daily routine.

She shared, "I take brushing my teeth seriously, so even at home, I have different kinds of toothbrushes, toothpastes, and dental floss."

What caught attention was her decision to carry two toothbrushes and two toothpastes instead of just one of each.

Kim Ji Won explained that the products may look similar, but they serve different purposes depending on what she feels like using.

She said, "They're actually different. One is a mint toothpaste with propolis, and the other is a slightly stronger toothpaste."

The actress added that she sometimes chooses which toothpaste to use based on what she has eaten.

However, she admitted with a laugh that her decision often comes down to her mood.

She explained, "I use them differently depending on what I've eaten. But honestly, I mostly choose based on how I'm feeling. I just trust that they have good ingredients."

Her casual explanation offered fans a glimpse into one of her everyday habits, showing that she pays close attention to her oral care routine even while working.

While carrying multiple dental products might seem unusual, Kim Ji Won appeared comfortable with her personal system and explained the differences between the items she regularly uses.

Meanwhile, Kim Ji Won is currently starring in SBS's Friday and Saturday medical drama Doctor X: The Age of the White Mafia.

Her latest behind-the-scenes video gives viewers a look at the practical items she keeps close during filming, with her collection of toothbrushes and toothpastes becoming a particularly memorable detail.
