Stamp Fairtex

Nadthawan Panthong (ณัฐวรรณ พานทอง, born November 16, 1997), known professionally as Stamp Fairtex (แสตมป์ แฟร์เท็กซ์), is a Muay Thai kickboxer and mixed martial artist from Thailand.

She is currently signed to ONE Championship, where she is the reigning ONE Women's Atomweight MMA World Champion.

She is the organization's first three-sport world champion, having also held the ONE Atomweight Muay Thai World Championship and ONE Atomweight Kickboxing World Championship.

These early years of Stamp's career were featured in the 2012 documentary, Buffalo Girls.

Going into her teenage years, Stamp took eight years off of Muay Thai due to being unable to find suitable opponents in her hometown region, in addition to there being a lack of women's Muay Thai fights being held at the time.

At 18, she moved to the Fairtex Gym in Pattaya, where she would also begin training in Brazilian jiu-jitsu.

Initially competing in the all-striking ONE Super Series, Stamp made her mixed martial arts (MMA) debut on October 11, 2018.

She won the 2021 ONE Women's MMA Atomweight World Grand Prix.

Her ring name is inspired by the Fairtex Gym in Pattaya where she trained from age 18.

Stamp's father is a former Muay Thai fighter who competed under the name Wisanlek Lukbangplasoy.

Stamp started practicing Muay Thai at the age of 5 in order to avoid bullying in school, with her father training her.

A year later, she would win her first fight by KO via knees.

She became a Muay Thai champion of a local stadium and a two-division Eastern Thailand champion.

In her ONE Championship debut at ONE Championship: Kingdom of Heroes on October 6, 2018, she challenged Kai Ting Chuang for the ONE Atomweight Kickboxing World Championship.

Stamp would win by unanimous decision, claiming her first ONE world title.

After being scouted by Rich Franklin, Stamp made her mixed martial arts debut on ONE Warrior Series 2 on July 19, 2018.

She knocked out Rashi Shinde with a head kick in just 19 seconds of the first round.

The victory earned her a contract with ONE Championship.

Stamp has won a gold medal at the 2019 Siam Cup BJJ tournament in the women's gi 58.5 kg class.

She was next scheduled to face Janet Todd for the inaugural ONE Atomweight Muay Thai World Championship at ONE Championship: Call to Greatness on February 22, 2019.

Stamp won the fight by unanimous decision to claim the ONE Atomweight Muay Thai World Championship and become ONE Championship's first two-sport world champion.

Stamp Fairtex would defend her ONE Atomweight Muay Thai World Championship against Alma Juniku at ONE Championship: Legendary Quest on June 15, 2019.

She retained her title by a unanimous decision victory.

In 2019, Stamp announced her intentions to continue to compete in mixed martial arts in ONE Championship, with the goal of becoming a ONE World Champion in MMA as well.

She made her ONE Championship promotional MMA debut against Asha Roka at ONE Championship: Dreams of Gold on August 16, 2019.

Stamp won by submission at 1:29 of the third round via rear naked choke.

Following the submission victory, she was given her blue belt in Brazilian jiu-jitsu by De'Alonzio Jackson.

Stamp was next expected to face Bi Nguyen at ONE Championship: Masters of Fate on November 8, 2019.

After dominating all three rounds with her Muay Thai-based striking, she would go on to win by unanimous decision.

After three straight mixed martial arts matches, Stamp would face Janet Todd for the second time to defend the ONE Atomweight Kickboxing World Championship at ONE Championship: King of the Jungle on February 28, 2020.

Stamp lost the title to Todd via a closely contested split decision, marking her first-ever loss in ONE Championship.

Stamp Fairtex was then scheduled to defend her Atomweight Muay Thai belt for the second time during ONE Championship: A New Breed on August 28, 2020, with her opponent being the Queens of the Ring Flyweight Tournament winner Allycia Rodrigues.

After five rounds, Stamp lost the title to Rodrigues by majority decision.

On January 11, 2023, it was announced that Stamp would face Anissa Meksen for the interim ONE Women's Atomweight Kickboxing World Championship.

The fight was cancelled after Meksen voiced her displeasure with how she was treated by the promotion.

Stamp next faced Puja Tomar at ONE Championship: A New Tomorrow on January 10, 2020.

Stamp went on to defeat Tomar by TKO at 4:27 of the first round via ground and pound.

Leading up to her fight with Tomar, Stamp had voiced her interest in facing Mei Yamaguchi, who she said possesses high-class wrestling skills, in order to test her own skill level.

She hopes a fight with Yamaguchi will help solidify her all-round MMA skills before she potentially challenges for a ONE World Title.

"My stand-up game is really good. It is strong, but my ground game still needs a lot of work," Stamp said, "I need to improve my ground game and get stronger because (reigning ONE Women’s Atomweight World Champion) Angela Lee is good all-around."
