Easy assembly
Color: Silver
Super easy assembly, one screw in tree trunk is unscrewed to place bowl and tree together - Phillips screwdriver needed. I bought the silver ring holder which perfectly suits my personality and decorative style. Can't tell you how wonderful it feels to finally have all of my rings off of my desk and stored in an easy to find place! Space saving is high on my list because I currently live in a 28' camper, so do not have my larger jewelry boxes in here with me. It only arrived today (7/28/2019) so this is with only a single days use, but am very pleased with the purchase and value for the ring holder - I was specifically looking for an inexpensive metal ring tree versus a plastic one.
