Our weight bags are made of steel shot sealed into polyethylene tubing, then covered with unbleached, unsized cotton knit tubing. They are "gently filled" so they have a flexibility that conforms to an object as needed. Lovely and tactile, they are one of our best selling items. We use them to stabilize items going on display that might have a bit of rock to them. We're sure you'll find many other uses for them.
Handmade in Rosemont, NJ, USA.
