Aluminum keeps this holder light in the hand and crisp in profile, which is what a slim candlestick needs. Its narrow footprint slips between plates and serving bowls on a crowded table, and metal takes the drips and handling that candlelight brings. Group a few down the middle of a table and the line reads better.
Slim and short, this wire holder is the small one in a stepped grouping, built from two stacked tiers. Iron gives it just enough rigidity to stand steady while staying nearly transparent on a table. Put it at the front of a cluster, or use a row of them along a windowsill.
