Promot P4-1540, Trodat 4911 Replacement Ink Pad - Red
A signature required stamp flags packets that cannot move until someone signs. This self-inking model prints Signature Required in a 9/16" × 1-1/2" red impression on contracts, delivery sheets, HR forms, and internall routing. Front desks and mailrooms use it so a signature line is not missed in a thick stack. The built-in pad is ready for repeat stamping; refill when the red lightens. Pair it with a custom signature stamp when the signer wants a consistent autograph after the document is marked. Clear alignment through the base keeps the mark in the same spot on every page.

Bought this after too many fragile shipments were treated like regular freight. The imprint is large enough to catch attention on brown boxes. Staying on our packing station for good.

I stamp Signature Required on outgoing parcels so handlers see the warning before tossing the box. Ink stays readable beside shipping labels. Clear handling cues with less writing.
