Comes with everything pictured, including extra container, which is a must for cleaning. I never used the detail nozzle.  I purchased new a few years ago, no longer need. Works good and has everything that was originally included. Message me with questions.

The FLEXiO® 590 handheld paint sprayer is a flexible solution for any type of home painting project. It can paint a wall 10 times faster than a brush or put a fine finish on furniture saving time and effort.

The FLEXiO 590 comes complete with two nozzles, one for big surface projects like walls, ceilings, exterior siding, and fences and the other for small projects and fine finishing on cabinets and trim. The power to spray unthinned coatings with adjustable control, full coverage and low overspray makes any painting project easier.

Cleaning is faster than a brush or roller with a few removable parts that rinse clean, and it all stores neatly in a hardshell case.

Covers an 8’ x 10’ surface in:

-Stain: 1 minutes
-Latex: 5 minutes
