Did not come in the box as it was pictured. It came in a Husqvarna box with the 585422145 number hand written on it and all the boxes with the chain specs were blank. I bought this as a spare for my new T435 Husqvarna saw with 12" bar. In the attached picture you can see that I have hand written the chain specs in the blank boxes for future reference.
Hope it's the right one when I need it.
