What's in Bundled Package A

Three core heat pack sizes:

Large Heat Pack — broad coverage for the back & larger muscle groups
Medium Heat Pack (260mm × 140mm) — back, abdomen & larger joints
Small Heat Pack (125mm × 90mm) — hands, wrists & on the go

Save $15 versus buying all three individually.

How it works

All three packs use the same sodium acetate technology — click the disc for instant, soothing heat. Each resets independently in boiling water.

Resetting your packs

Each pack resets separately — or drop all three in the same pot of boiling water for 10–15 minutes. Remove when completely clear.

Is this kit right for me?

Ideal if you want coverage for the full body, or you’re new to Shin Bio and want to try the core sizes. For chronic lower back pain, consider Bundled Package B which adds the ceramic belt.
