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.

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.

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

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.

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 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.

Stamp next faced Puja Tomar at ONE Championship: A New Tomorrow on January 10, 2020. Stamp defeated Tomar by TKO at 4:27 of the first round via ground and pound.

Leading up to her fight with Tomar, Stamp voiced interest in facing Mei Yamaguchi, whom she said possessed high-class wrestling skills, to test her own level. She said she hoped a fight with Yamaguchi would help solidify her all-round MMA skills before she potentially challenging 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."

Stamp next faced Sunisa Srisen at ONE Championship: No Surrender on July 31, 2020. She extended her winning streak to five with a first-round TKO of Srisen.
