The main centre for the tortoise shell crafting is in Andhra Pradesh district of Vishakapatnam where chiefly trinket boxes are made in combination with bone. The shell surface of the box is covered with intricate designs of bone fretwork so that the orange glow of the shell can be seen through this perforated lacy pattern. The designs include fine geometrical patterns, epic figures and animals fringed by floral motifs.

A combination of horns, bone and tortoise shells are also combined to make products at Vishakapatnam and Secunderabad. Bone is also combined with sandalwood, ebony and tortoise shells to create intricate patterns of fretwork that are mounted or inlaid to make ornate octagonal jewel boxes with the bone net cover.
