I’m using this wooden jewelry tree as a display for my fun earring collection, and I love how cute and creative it looks! It comes in three pieces and is easy to assemble, though I did need a hammer to tap the pieces flush. I wish the earring holes were spaced a bit farther apart in some areas, but overall, it’s a charming and functional stand. Makes a great gift for any jewelry lover!

Not worth the money

Style: TREE

This is certainly NOT worth the money. It arrived broken and not worth fixing. Don't waste your money.

Quality, CLEAR, versatile divider/containers.

Size: 12 Pack, Color: Clear

CLEAR and not cloudy! Smooth edges, well made, flexible enough not to break easily but gives support and structure to the contents. Very versatile sizes too! The included rubber-like stick-on feet is a brilliant addition. Just buy ‘em!
