------------------------------------------------------------------------------------------------------------------ 【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. ------------------------------------------------------------------------------------------------------------------

【NANO-K Variable ND Filter】The K&F CONCEPT ND2-ND400 variable ND filter allows for 9 levels of light reduction, from ND2 to ND400, and the density of the neutral density filter can be adjusted as needed to suit various lighting conditions. (This variable ND filter is not suitable for use with telephoto lenses. A lens hood cannot be attached.) There is a mix of old and new exteriors, but the internal components are the same. 【18-Layer Coating】This variable ND filter is made of high-quality optical glass with 18 layers of transparency-enhancing coating on both sides, effectively reducing reflected light from the filter surface. 【Proprietary Lens Cap】This lens cap features a high-quality design with an innovative non-spring structure, avoiding issues such as spring deterioration. Its inner-type design allows it to fit a variety of lenses. [Includes 1 vacuum-packed cleaning cloth] The included cleaning cloth is made of microfiber and will not damage the coatings of optical equipment such as lenses and lens filters. It can also effectively remove stubborn oily films and sebum stains. [Precautions] Variable ND filters are prone to producing X-shaped unevenness when set to the higher settings. The location of the unevenness will vary depending on the type of lens and focal length . If you continue to rotate the filter, the shadow will disappear naturally. This phenomenon is not a quality issue, but a natural physical phenomenon caused by the rotation of the variable ND filter.
