standing next to Pullip, comes up to her shoulder. Dal's body articulation is similar to Pullip's. Her eyes move from side to side, but they do not close. Dals can be customized, just like Pullips and Taeyangs. Jun Planning announced in the beginning of 2008 that a new Dal would be released every month. Since then, the manufacturer has occasionally skipped a few months between releases; however, to date, there have been more than 75 Dals released in total. Byul Byul was introduced in December 2008, with the first version named Eris. Byul shares the Dal body type but has a different face sculpt. She is profiled as Dal's 13-year-old best friend who has secretly lost her heart to Isul, Pullip's little brother. Just like Dals, Byuls cannot close their eyes, and their height is 26.3 cm. A new Byul is released approximately every two to five months. Since 2008, there have been more than 25 Byul releases. Isul Isul is Pullip's 15-year-old brother and was first released in February 2011. The debut Isul was named Apollo and was part of the Steampunk series of Pullip dolls. Like Pullip, Isul has eyes that can move from side to side and eyelids that can blink and close via levers on the back of the head. Isul is profiled as a high school student in San Francisco who likes to play soccer. As a prodigy, he is a fan of reading university literature. In personality, he is said to be very calm, tender and helpful. Isul is 29.5 cm tall. Isul is released approximately once per month, but the Groove sometimes skips a month or two between releases. Since 2011, there have been more than 30 Isul releases. Yeolume Released in February 2013, Yeolume is Pullip's future daughter and the newest addition to the Pullip line of dolls. Yeolume is 26 cm tall, and the first release, named Podo, wears a school uniform with a pink and blue bow. According to her biography on the official Pullip website, Yeolume is 10 years old and is an elementary school student. Yeolume is approximately the same size as Dal and, like Dal and Byul, her eyes moves from side to side but cannot close. However, unlike Dal and Byul, the design of Yeloume's body is very different: she has minimal articulation points, and her body somewhat resembles a Little Pullip (though larger in size)
