Here's the product description:

THERAvantage Stainless Steel Gua Sha — Glider, 8" x 1"

The Glider is the workhorse of the THERAvantage stainless steel line — an 8" long, 1" wide instrument designed for broad, efficient soft tissue treatment across the full body. Where natural material tools carry classical association and aesthetic appeal, stainless steel brings a different set of practical advantages: it can be sterilized completely between patients, it never absorbs oils or residue, it maintains a consistent edge indefinitely, and its thermal conductivity allows it to warm quickly to body temperature during treatment, producing a smooth, comfortable gliding sensation across oiled skin.

At 8" the Glider is the longest tool in the collection and covers the most ground per stroke — ideal for long sweeping passes down the paraspinal muscles, along the IT band, across the hamstrings and calves, and through the broad fascial sheets of the thoracic and lumbar back. The slim 1" profile keeps strokes controlled and precise while still covering meaningful surface area, and the smooth curved edges transition seamlessly between different tissue zones without catching or dragging.

This is the tool of choice for practitioners who prioritize clinical efficiency and hygiene, and for patients who prefer the no-maintenance simplicity of a stainless instrument they can clean quickly and use repeatedly without any special care requirements.

The Glider is also well suited to instrument-assisted soft tissue mobilization (IASTM) technique — a modern physical therapy application that shares significant overlap with traditional gua sha in its approach to fascial restriction, scar tissue mobilization, and chronic myofascial pain patterns.

Dimensions: 8" x 1" x 0.19" Material: Medical-grade stainless steel Best for: Paraspinal muscles, IT band, hamstrings, calves, thoracic and lumbar fascia, IASTM, general full-body soft tissue treatment
