The coolest spice rack ever. Four pre-labeled Erlenmeyer flasks hold the basics: Salt (Sa), Pepper (Pe), Sugar (Su), and Oil (Oi). The Salt and Pepper flasks are shakers; the Oil has a pour spout with cap. Nine test tubes come with 54 labels to choose from, like Pa for Paprika, Or for Oregano, and Mu for Mustard. Flasks and tubes are glass with rubber stoppers, and a stainless steel tray corrals them all on your counter. Large flask about 5¾" high, test tubes about 3" high, tray about 10½" wide.
