Extra Thick Solid Brass Ball Chain Thick ball chain for necklaces. Length can be freely adjusted with nippers. Comparison with the thinner (though not thin) 3mm ball chain in the image. Length: 70cm, Thickness: 4mm Material: Brass. Not plated, so it shines the more you polish it. Available in 40cm/50cm/60cm/70cm lengths separately. Fine length adjustments are also OK. Please comment. If you can't find other lengths, I will create a dedicated page. Other necklace chains → #chein1942el Do not use if you have a brass allergy.
