Review on 💎 HENGDA Upgraded Manufacturing Jewelers Portable: Enhancing Jewelry Making Efficiency by Charles Galan

Looks very high quality works well. NOTE: It must be lubricated with oil before use for the swivel function to work. Apply a few drops of machine oil around the side lever and drain; then turn upside down and apply a few drops of oil around the bolt/nut from below and allow to drain; Apply a few drops of oil around the seam where the two pieces meet (where it pivots) and let it drip off. After that, the hinge should work smoothly.
