Amazing. Great quality. Super sturdy. The color is vibrant and just like it was pictured. Smooth surface. Even comes with 2 littles keys! So cute. No setup, just pull it out of box and load it up! Love all the little drawers helps keeps everything organized. Very stable on top of dresser. Great for price.

Strong well made but ..

Color: Gold

Coring tool broke as soon as I tried to loosen the top. As far as a tube goes it is great. Seals tight, solid Aluminum throughout. You could throw this off a tall building and it would be fine afterwards.
