Pla-Board 3mm B4, model building sheet, white

Pla-Board 3mm B4 is a white model-building sheet made for scratch construction, custom fabrication and clean structural work in hobby projects. The 3 mm thickness gives the board substance for parts that need more presence than thin sheet material, whether used for bases, spacers, panels or shaped inserts. The B4 size measures 257 x 364 mm, leaving enough surface for larger cut sections, repeated templates or several smaller components from one board. The flat format supports careful measuring before cutting, and the plain white surface keeps pencil marks, layout lines and edge checks easy to read during fabrication. Supplied as 1 board, it fits focused modification work where a single panel is the right starting point. On the bench, the sheet can be trimmed into straight strips, shaped into custom sections or used as a backing layer for diorama structures and model details. It also suits repair and conversion tasks that call for a clean, uniform board with consistent 3 mm thickness across the full panel.
