Large, quality pieces. Ebonised boxwood. Weighted and felted. 4 inch (102 mm) king. Ideal for a 23 inch (60 cm) board. Quality large chessmen made from boxwood and ebonised boxwood. Ebonising is a process of treating natural boxwood to look like real ebony. It\'s a long and painstaking process but the results are certainly worth the wait. Heavy, beautifully finished chessmen Because of the quality of finish and weight of the Frankfurt Series Chessmen they have become one of the best sellers on the Regency Chess website. In fact, the solid feel in hand is a compliment we hear regularly from customers. These large pieces are nicely weighted and naturally polished with plush flocked bases in green. They are great for home and tournament use and would be suitable for pairing with our 23 inch (60 cm) chess boards.
