These are a square .04 ounce bottle with black royal cap.  An another equivalent measure is 2.43 teaspoons, and .64 dram. Great for filling with perfumes. This is for 20 of them with matching caps. The caps have a plastic clear dimple sealer in them. Good thick quality looks like ice cubes ! They measure 5/8 in wide, 1 1/4 in across front, top opening 1/4 in , 2 in tall without cap, 2 1/2 in tall with cap.
