The R-0040 sits between our two most popular diameters, 38 mm and 42 mm. Distributors order it for seal layouts that need more text room than 38 mm offers without moving to a larger shell. The round line covers 9 diameters — 12 / 19 / 25 / 30 / 38 / 40 / 42 / 45 / 50 mm — all sharing the same mould system used by our two house brands.

  • CHIMEI ABS main body for impact resistance and a clean surface finish
  • Laser-engraved stamp surface for sharp, consistent imprints
  • Built-in replaceable ink pad: press the lock and slide out — clean hands
  • Lock button, display window cover, chip hole, support bracket, non-slip mat, blind panel

FAQ

Why choose 40mm instead of 38mm or 42mm?

40 mm gives extra room for a longer company name or a second text ring without moving up to the larger 42 mm shell. It is a common OEM size for private-label seal programs.

What fits on a 40mm round stamp?

A logo plus a full company name ring, or a logo with two short lines of text — for example a company name and a telephone or license number.

What is the MOQ for the R-0040?

Standard MOQ is 100 pcs per model, and trial orders are negotiable. Samples ship in 2 working days; bulk production takes 3–5 working days.

Can the ink pad be replaced?

Yes. The pad slides out from the side slot — press the lock, pull the old pad out and push a new one in. No tools and no inky fingers, about 10 seconds.
