---------------------------------------------------------------------- 【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. ---------------------------------------------------------------------- [Product Contents] Skateboard trucks are the metal parts that connect the deck (board) and wheels (tires). Two pieces are needed for one skateboard. Please note that screws to secure to the deck and bearings to be attached to the wheels are not included. [Materials/Manufacturing Method] By slowly casting ASTM 356 aluminum using the gravity casting method, we have achieved a strength that is about twice that of conventional trucks. [Lightweight] The kingpin (bolt in the center of the truck) and axle are made of heavy steel, and both are hollow. The back of the base mount has also been boldly hollowed out, resulting in a significant weight reduction. [Color] The 4.5 size is available in two colors, green and purple, while the 5.0, 5.25 and 5.5 sizes are available in black. [About the kids' version] Based on the know-how we have gained from developing many super kid skaters since the 1990s, the 4.5 size, which is intended for younger children with low muscle strength and stamina, has been made even lighter with a completely different shape design from the other sizes to reduce the strain on the joints and other parts of the body when performing lateral rotational tricks such as ollies, shove-its, and 180s.
