Spizer Studio’s square grid Stack (insert refill), named in the spirit of sketching perspective - of seeing structure emerge from space. Whether you’re mapping an idea, designing a layout, or enjoying the rhythm of alignment, this insert offers balance and clarity without confining your creativity.

Each Stack includes 48 pages of 80gsm paper, with light grey grid lines, and saddle-stitched with care.
