Need to quickly and neatly number documents, tickets, forms, or dates? This Trodat self-inking numbering stamp is the professional tool for the job. The model is B4846, and it prints numbers that are 4mm tall – a clear, readable size for most paperwork. The big convenience here is that it's self-inking. The ink pad is built right into the stamp (this one comes with a white ink pad), so there's no messy separate ink pad to deal with. Just press down, and it stamps and re-inks itself in one motion. The screwdriver-style head lets you easily rotate and set the next number in the sequence. It's compact, durable, and a huge time-saver for offices, warehouses, libraries, event organizers, or anyone who does a lot of repetitive numbering. Trodat is a trusted brand for a reason – their stamps are reliable. It even comes with a 12-month guarantee. Ditch the messy handwriting and get consistent, professional-looking numbers every time with this handy little tool.
