+# Custom Rubber Stamp Specification — 15×15 5mm Grid
+
+Target supplier: UK custom rubber stamp manufacturer (Stamps Direct, Rubber Stamp King, Personalised Stamps, Cut By Beam, Stamp Design 4U, English Stamp Company, or Get Stamped — all deliver to UK; select one based on price/speed).
+
+## Dimensions & Layout
+- Stamp face (impression area): **75 mm × 75 mm** (3" × 3")
+- Grid: **15 columns × 15 rows** = 225 boxes total
+- Each box: **5 mm × 5 mm** square
+- Line weight: thin black lines (≈ 0.5 mm) separating boxes; no thick border
+- Orientation: grid aligned to stamp edges, horizontal lines parallel to long sides, vertical lines perpendicular
+- Margin inside face: minimal (boxes run near edge; <1 mm padding) — specify if you prefer a 2 mm clear border
+
+## Design Format (provide to supplier)
+- Simple black-and-white line drawing (SVG or high-res PNG, 300+ DPI, transparent background)
+- Only black lines on white; no shading, no gradients, no colour
+- File name: `stamp-15x15-5mm-grid.svg`
+- Lines must be uniform thickness; boxes must be square (not rectangular); grid must be square, not stretched
+
+## Material / Mount
+- **Stamp type:** Traditional rubber (wood-mounted, separate ink pad) OR self-inking — specify your preference (traditional is more flexible for custom line work; self-inking is more convenient for repeated use)
+- **Rubber quality:** High-grade, laser-etched or traditional cut to maintain clean 5 mm edges
+- **Size to order:** If supplier requires selecting from dropdown: choose the closest standard size ≥75×75 mm and note "custom 75×75 mm face" in order notes; if they offer custom dimensions, specify exactly
+
+## Proof / Approval
+- **Require digital proof before manufacture** — confirm the 15×15 count, 5 mm box size, and line weight match
+- Do NOT approve if proof shows stretched, rounded, or uneven boxes
+- Confirm proof dimensions in mm
+
+## Delivery / Shipping
+- **Destination:** UK delivery address (specify your postcode at checkout)
+- **Timing:** Standard UK delivery (3–5 working days after approval; same-day dispatch available at some suppliers if approved before 11am/12pm)
+- Confirm with supplier that they can meet exact 75×75 mm and won't round to nearest standard size
+
+## Price Reference (approximate — confirm with supplier)
+- Large custom stamps typically £20–£50+ depending on size, rubber quality, and mount type; custom dimensions may add a small premium; some suppliers offer free UK delivery over £35–£40
+- If price is a concern, ask for quote before confirming order
+
+## Notes / Extras (optional, specify if you want them)
+- Text below or above grid? (e.g., "15×15", your name, date) — NOT included by default; specify if needed
+- Rounded corners on stamp face? No — square corners preferred to keep grid aligned
+- Double-sided? No (single face sufficient)
+
