Freebird FlexSeries Pro Blade Refill: Generation and Fit

The FlexSeries Pro blade assembly is for FlexSeries Pro. Freebird explicitly excludes the original FlexSeries; check your shaver generation before buying.

Freebird explicitly excludes the original FlexSeries from the Pro refill: the two generations do not use the same replacement assembly. BL2B-1-US-EA-1, BL2B-1-US-EA-3 and BL2B-1-US-EA-6 are distinct commercial pack references within the Pro family, not evidence of additional shaver generations. Compare the included assembly and pack quantity on the exact offer.

FlexSeries Pro refill: the original FlexSeries is excluded

Sources checked 2026-10-07

Freebird’s replacement-assembly FAQ says the FlexSeries Pro blade assembly is compatible with FlexSeries Pro and excludes the original FlexSeries. Check the generation printed on your shaver before choosing this refill.

A product destination is provided for the Pro assembly, while the original FlexSeries has a separate part page. The similar family name and appearance do not create interchangeability between those two assemblies.

Choose the matching generation

Use the original FlexSeries page if that is the shaver you own. For FlexSeries Pro, compare the assembly and included parts against the manufacturer page.

Manufacturer reference evidence and source qualifications

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.
