Roll your own Henna Cones with convenient pre-cut triangles of  assorted printed and patterned polypropylene wrap.
~Supercones~
Inexpensive, convenient, SHINY!

 

You can roll a supercone thin and tight for hair-fine lines, or loose for thick lines.  Supercones are kind to your hands, unlike thumb busting jac bottles.  With supercones you don't have to pick out clogs, you just pinch the clog through the tip!  Supercones ROCK!

However, finding nice mylar, a clean table, good ruler, and sharp scissors to cut cones is a nuisance.  Your cat will want to sit on the mylar and hair it up, your good scissors may have been used to cut a garden hose, the ruler disappeared at the back of the drawer, and if you can find a clean tabletop, you are a better housekeeper than I am.  And, all that takes time.  So, instead of throwing out the cat, sharpening the scissors, finding the ruler, and cleaning the house (yuk), how about ordering  a packet of perfectly cut triangles, in all sorts of colors and shiny patterns ready to roll  ..........  at 20 cents each ..... very convenient!  That'll roll you through a lot of henna!
