This is a lot of six genuine Bambu Lab Empty Filament Spools.
Four are white, two are translucent.
I print mainly PETG-CF and Bambu Lab does not sell refills for PETG-CF.

These spools may have the cardboard core and RFID for PETG-CF, but these can easily be removed if you don't need them. One has RFID for PLA Tough.

Although not pictured, the matching Bambu Lab boxes are included.

Excellent previously used condition - Only used once.
