【Soothing Heat】 - Keep your clients cozy and comfortable before or during a massage with our Medium Oval Shape Basalt Massage Stone, which reaches a perfect temperature of 113℉ / 45℃. Use it to warm those key areas like the spine, stomach, chest, palms, and shoulders. 【Full Body Massage】 - Our energy stones are perfect for a variety of massage techniques, including long strokes, circular movements, vibration, tapping, and kneading, to provide a soothing massage on your arms, legs, thighs, calves, neck, back, lower back, and stomach. Melt away stress as our natural healing stones glide over your body. 【Ergonomic Design for Optimal Comfort】 - Our uniquely rounded and narrower edges have an added benefit-they can be used to apply concentrated pressure and knead tense muscles during treatments. Additionally, the flat part of our design provides excellent support for the neck or can be used to securely position the hot stone on the abdomen or lumbar area. 【 Natural Volcanic Lava Basalt】 - Made from natural volcanic lava basalt, our basalt is rich with iron and magnesium. Each piece of this massage stone set is expertly shaped and polished using traditional handcraft techniques, with no wax, dyestuff, or chemicals applied. 【 Excellent Heat Retention】 - These natural massage stones measure 6.6 cm x 4.9 cm x 1.8 cm and come in packs of 12. Experience the soothing warmth for over 25 minutes as these stones hold heat exceptionally well. Once heated to a cozy 60°C / 140℉, they will take around 25-30 minutes to cool down to a comfortable 37°C / 98℉. (Note: based on a room temperature of 25°C / 77℉)
