New Panther Mini Range which will eventually include 8"/10"/12"/14"/16"/18" versions for Stihl/Husky/Echo/Makita [and likely others but you need to sniff out a 1/4 drive sprocket]. The original 1/4. 043 picco chain was the Stihl 3670-71PM3 and this chain was ground breaking in it being the smoothest, thinnest and cleanest cutting chain on the market.
