Tokyo Science Fluorescent Mineral Specimen Set Wave 10 (Long Fluorescence, Species)

---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- We collected 10 mineral specimens that fluoresce under long-wave ultraviolet light (320-400 nm). Kunzite (lithium pyroxene), amber, brown calcite, manganese calcite, fluorite Hackmanite, ruby corundum, adamite, sodalite, wernerite Box dimensions: 203 x 87 x 35 mm A long-wavelength ultraviolet light (black light) is required. Packaged in a cardboard box. Box dimensions: 203 x 87 x 35 mm. The minerals in this specimen set fluoresce in response to long-wave ultraviolet light. Please prepare a long-wavelength ultraviolet light.
