【Professional-Grade Ring Stretcher Tool】
Engineered with reinforced chrome-plated steel construction, this ring stretcher tool offers superior durability for frequent use. Unlike cheaper alternatives, our mandrel maintains precise alignment during stretching, preventing ring warping. The polished chrome surface ensures smooth operation when resizing gold, silver, and other soft metal rings.

【Complete Jewelry Workshop Solution】
This 3-piece ring stretcher tool kit includes: (1) Multi-diameter steel mandrel (sizes 6-10), (2) Tapered expansion pin (3) Heavy-duty alloy base. The included anti slip base can provide stability during the adjustment process, making it very suitable for jewelers who need reliable ring size adjustment equipment.

【Simplified Sizing Process】
We have improved the design of the impact surface, reducing the force required for expansion by 30%. The tapered pin gradually stretches the ring, and the size does not suddenly jump, solving the problem of "excessive stretching" for users. Even beginners can achieve professional results with minimal practice.

【Smart Storage & Maintenance】
The knurled grip surfaces prevent rolling and accidental drops. Its compact size makes it suitable for mobile jewelers' kits, while its sturdiness allows for bench use as well.

【Safety-First】
While excellent for solid gold and silver bands, we recommend caution with:
Rings below 1.2mm thickness
Any setting with gemstones or enamel
Titanium/tungsten rings
