Very large and heavy. Seems great quality. Has a base and the planter sits inside another box to do the self watering. Looking forward to putting this on my patio.  Not using it as a window box. Had a small scratch in the plastic when I unpacked it.  I don’t understand why there seem to be built in places to put brackets but it doesn’t come with any. How do you find the correct brackets if you do want to hang it up
