# cups (std. length):
Waterflow Index™ 5/5
An exclusive addition to our aged square cups designs.
This Medium square cup adds a distinctive "slotted" cutout design. Made
of pure copper, with a folded lip along the top for stiffness,
each cup is individually welded together by hand.
The heat of the torch
adds the unique coloration (aging effect); this is not
a chemical coating or paint. This chain looks a hundred
years old right out of the box! Will easily handle heavy
To prevent damage in transit and reduce packaging volume, the upper wires are shipped separately from the cups, so some assembly is required -- it takes just a few minutes with no tools. See our Resources page for a video guide: https://rainchains.com/links.html.
Comes with a copper V-hook for easy installation.
