This is an auction for the "ProDetail" detail trimmer head, an accessory for the brown beard trimmer, the top-of-the-line "BT9420 Brown Beard Trimmer Series" with PRO blade specifications. *Please note that this listing is for the trimmer head only, and the main unit is not included. I'm not sure if it's the latest model, but I couldn't find this head sold separately. I don't use this type of head, so I'm offering it to someone who is looking for it. Replacement blades are consumables, and this detail head with a full metal blade seems to only come with this model, so how about it? By the way, I have the impression that it can be used not only for "BT9420" but also for "BT7420" and "BT5440", but please note that this has not been confirmed by Braun. Recycled materials may be used for packaging. Thank you for your consideration. Type...Beard Trimmer #Clippers #MultiTrimmer #MultiGroomer #Brown #BRAUN #ReplacementBlades Type...Beard Trimmer
