Handmade and made to order refillable resin circuit board notebook. These notebooks are made using resin, mica powder and a circuit board trace overlay. The notebook comes with 35 sheets (70 pages). You get the choice of the circuit trace color (gold, silver or copper) and the background color (see color chart in photos for options). The notebook also comes with a plain matching back panel. The binder rings are available in either gold or silver, which unless specified in the personalization box, they will match the circuit trace color chosen (copper will get gold rings unless specified). These notebooks are also personalizable. If you would like something written on the notebook, please type what you would like in the personalization box. If nothing is in the personalization box, the notebook will come with just the chosen background color and circuit traces.
