The LEGO Mindstorms NXT 2.0 (8547) is a retired set that includes 619 plastic pieces and is designed for children aged 10+. It is a STEM toy that allows kids to build and program robots. The set is missing the original CD, but the CD contents are available from LEGO. The set was released in 2009 and retired in 2012. It comes in a box with a User's manual and a test pad and was manufactured in Denmark, China, Hungary, and Czech Republic.

Parts are in very good condition. The set is missing a CD that comes with a new set. You can download the CD contents from LEGO here: https://education.lego.com/en-us/downloads/retiredproducts/nxt/software/.

I counted the parts, and 445 of the 619 parts are in the larger plastic bags.  There are two sealed original bags of smaller parts that should account for most if not all remaining parts. Comes as pictured.
