These are splendid storage containers. Made from a cellulose propionate, they won't break if you drop them.
The 3/8" and 1/2" sizes are 6" long, and are particularly good for storing slender items such as fret-saw blades. They are also excellent for small tacks and brads, as the narrow tube allows you to decant a few pieces at a time.
The larger sizes are 4" long and can hold a wide variety of items from screws and brads to hardware and bits.
All have screw-on lids (various colors, depending on supply). Hundreds of uses in the shop and home.
Sold in packs of 10 for diameters under 1" and packs of five for 1" plus, or as a set of 55 tubes – one package of each size.
Made in USA.
