Classic and useful.
Color: Black
I purchased to gift my son for his apartment. It is both attractive and useful. The weighted base makes it functional and balanced, and all for a very minimal price.

Budget friendly and useful!
Color: Black, Color: Black
Light weight affordable and still nice. Could be a little bit heavier at the base, I really like it so far. Seems pretty sturdy, definitely will need to check in to see the longevity of the product. Overall good budget buy.

Use for canning rings
Color: Black
I bought this to hold my canning rings and it worked great. The smaller arm holds my wide mouth rings and the larger one holds the regular ones. When I’m canning, I’m able to move the whole thing into the kitchen due to its light weight and use what I need. Once I’m done with the rings, back they go.
