Buying Guide
Size matters: choose an impression area that matches your typical documents. For dense forms, a medium size often works best; for compact spaces, a small stamp is ideal. Ink color considerations: black is standard for legal docs; blue is common for business banking; other colors add emphasis but may not be suitable for formal documents. Self-inking vs. traditional: self-inking offers clean impressions and convenience, while some users prefer mechanical stamps with refillable pads for custom inks. Customization method: ensure you can upload a signature image or enter a font clearly; check supported file formats and maximum file size. Maintenance: refillable inks and pad replacement affect long-term cost and usability.
