How to use

Remove the empty cartridge from the SX217 pen body according to the pen's disassembly method, insert the SXR-C7 refill fully into the pen barrel until it seats securely, then reassemble the pen. Verify the tip is properly aligned with the pen tip opening and test on scrap paper to confirm ink flow before regular use. Dispose of the spent cartridge in accordance with local waste regulations.

Usage recommendations

Store refills capped or in their original packaging in a cool, dry place away from direct sunlight. For best performance, use on typical paper grades; very absorbent or coated papers may affect drying time or line appearance. If ink flow is slow after installation, gently scribble on scrap paper to prime the tip.
