Please confirm my profile before purchasing. (⋆ᵕᴗᵕ⋆).+* ❁❁❁❁❁❁❁❁❁❁❁❁❁❁❁❁❁❁❁❁❁❁❁❁❁❁ ★ This is a rare terahertz rod, a tsubo-pressure massage rod. Originally intended for tsubo-pressure, I was looking for it to put in a plastic bottle, so I hope those of you with the same idea or purpose will take responsibility for yourselves (⋆ᴗ͈ˬᴗ͈)” (I tried putting terahertz in water to drink, as I found on the internet that it makes terahertz wave water) Of course, I think it's also perfect as a regular terahertz rod (*^^*) ★ I have many other items for sale, and if you purchase sets or bundles, you will get a small discount, so please consider it (⋆ᴗ͈ˬᴗ͈)” Size Length: Approximately 74.6mm Width: Approximately 17.5mm 【Terahertz】 ♥ The most significant feature of terahertz ore is that it is an artificial ore made by human hands, not a naturally occurring ore. Terahertz ore is high-purity silicon extracted by melting quartz at high temperatures and then recrystallized. It is widely used in medical and industrial fields, but in recent years, its application has expanded to accessories and health promotion goods. Terahertz ore is a silver-colored power stone similar to Gibeon and hematite, and it is said to emit a frequency that vibrates about one trillion times per second. Terahertz waves are a type of electromagnetic wave, emitting a long frequency, between 1 trillion Hz and 100 trillion Hz, with a wavelength of 3μm to 1000μm, and have the properties of both light and radio waves. Its vibration is said to promote blood flow, relieve stiffness, and promote beauty and health. According to NASA, these terahertz waves are "transmission wavelengths" that penetrate matter and reach human cells, so they have an activating effect, and research is currently underway worldwide on this stone. #nyanta Please check profile always Other #nyanta Please check profile always #nyanta Please check profile always Terahertz ※ (Please understand that this is just an amateur measurement) ※ Please understand that the actual product may differ slightly from the photos taken by an amateur. ※ Please understand the small scratches, inclusions, dents, and partial polishing deficiencies unique to natural stones.
