“Whoever designed this knew exactly what they were doing."

An $11 facial cleansing brush from Kmart has caught the attention of female shoppers, but not for its skin cleaning promises.

The battery-operated face product has caused social media users to get excited because of its shape and vibrating feature that might appeal to another part of the body.

Australian TikToker @methgirlfriendd shared the important PSA with her viewers in a video revealing the bargain skin care tool with the caption, “Run don't walk to Kmart for $11".

"I went to Kmart and saw this facial cleansing brush. Well, I mean... it might work," she said before turning it on and putting it on the bathroom vanity.

The device then starts to move around vibrate loudly against the counter.

The now-viral video has been viewed more than 1.6 million views within a week.

In a comment underneath the clip from six days ago, the TikTok original poster Emily wrote, “review: 11/10 must buy.”

In the comments under the clip, hundreds of other women knew exactly what Emily was trying to put down.

“Whoever designed this knew what they were doing,” one woman wrote.

While another person commented, “I have a sudden interest in skincare.”

A third viewer said, “I’m going to Kmart tomorrow.”

The official account of skincare brand Frank Body also left a comment and wrote: "Is it still in stock? (Asking for a friend)."

While Vush HQ TikTok - a brand that sells adult pleasure toys - replied, “Now I’m panicking... because I’m going to lose my job”.

While others suggested the bargain retailer knew a thing or two about designing products for women, suggesting the store’s coffee grinder excited shoppers in a similar way.

“Between that and the coffee grinder. Whoever is creating these for Kmart know what they’re doing,” one person wrote.

And a second stated, “Probably the same person who designed the coffee grinders.”
