It looks like these may be the replacement for the discontinued Sailor Promenade. Sailor Promenade Shining Red had model numbers 11-1031-x30, and Promenade Shining Blue had model numbers 11-1031-x40, while Promenade in black with silver trim had model numbers 11-1033-x20; so the Profit Lite cannot be said to be the same pens as the Promenade. Moreover, Broad, Zoom and Music nibs were not available on the Promenade models, and Extra Fine only available on the Promenade in black with gold trim, so this would be an expansion. I'm a little surprised that the MSRP for the Profit Lite is the same as that for the Promenade (for the nib sizes that were available on the latter).
