R-0040 Round Self-Inking Stamp · 40 mm
The balanced mid-large diameter of the round series — chosen when a 38 mm layout feels tight but 42 mm is larger than needed. Taiwan CHIMEI ABS shell, precision laser-engraved surface, and a replaceable ink pad that slides out — no inky fingers.

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.
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.
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.
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.
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.
