Round or Rectangle bookmark is made of brass with photo etched. You can add soft enamel or not.
The pattern on photo etched pin is created through chemical corrosion, not by die stamping. Compared to die stamping, the depth of recessed part is relatively shallow. Photo etching cannot achieve a 3D effect because the pattern is corroded, and the depth of the recess is consistent.
Typically, the material thickness is 0.8mm. Besides brass, aluminum and stainless steel is also workable.
