Source records captured 2026-10-27

Compare IZUMI references SO-V578, SI-V55 with their recorded sources below. Keep every regional suffix, component and pack marking when checking an offer.

A shared family name does not establish that every pack, component, colour or generation fits the same device.

Additional exact references and regional packs

These IZUMI codes are kept separately so that a regional pack, component, colour or quantity is not silently substituted for another reference. A model listed for one reference does not establish fit for every reference shown here.

Reference sources and qualifications

A manufacturer may confirm a part number without confirming that it fits your exact shaver. Use the model list and market restrictions above for that decision. Retailer listings describe what is sold; they do not replace manufacturer fit evidence. Dates below identify the recorded source reading or earlier snapshot, not a new test of the product. An unknown date remains unknown.
