・This jacket transforms your favorite ballpoint pen into the ultimate writing instrument. *Wrapping bag not included. ・The number of refills (ink cartridges) compatible with this pen jacket, without modification, exceeds 950 for Japanese products and 1000 when including foreign products. ・The pen jacket consists of only one part. The pen tip is attached to the fixing adapter, securely holding the refill in place. This eliminates wobble and allows for smooth, accurate writing. ・The main material is made of A6063 aluminum alloy or titanium alloy. SUS304 stainless steel is used for joints and areas requiring strength. The stainless steel is machined from a solid body, contributing to improved writing comfort. ・This jacket supports the pen in the middle, creating a balance where the pen tip is slightly heavier. The weight is also appropriately balanced – not too light, not too heavy – to provide a pleasant tactile feel.

【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.
