Flexible and loosely packed with micro-grain galvanized steel pellets, weight bags provide a great way to apply weight to both flat and peculiar shaped items. Developed to go inside tall thin necked vessels to help stabilize them while on exhibit, these versatile bags will be suitable for many conservation and restoration applications. The steel pellets are sealed into 2 mil polyethylene tubing which is then covered with inert, 100% polyester white stockinette, which is less likely to attract and hold dirt than the old cotton-sock covering. Heat sealed for a strong, clean, smooth and attractive edge that won’t fray and unravel like the old, stitched-edge version. Price each.
