Removable & Reusable Spool: Designed for Bambu Lab 3D printer filament refills. Easy to assemble and disassemble, it's cheaper than disposable spools, saves space, and reduces waste. I was using it for PLA Matte, but by replacing the stickers included with the spool-less filament and the RFID tag, it's compatible with various filaments. *Note: This product is for empty spools only, filament is not included. Genuine Empty Spools x 3 *Reference: Bambu Official Online Store Price 2,080 yen x 3 = 6240 yen equivalent Everything in the photos is included.
