Lab Notebook

A hardbound a4 laboratory record notebook, portrait, 0.21 x 0.30 m with a squared spine and a visible page block, lying flat on y=0 inside one 0.3 m tile, a ribbon marker and a plain pen as filler.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
