【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. ``Black Panther'' Submarine – Build the Lego Marvel King Namor's Throne Room (76213) and set off on an underwater exploration Marvel Characters – Assemble the submarine and throne room, then start your adventure with 3 minifigures (Shuri, Attuma, and King Namor), seaweed and fish accessories Various ways to play – Enjoy pretend adventures set in submarines and temples For Marvel Fans – Perfect birthday or Christmas gift for superhero fans (Ages 7+) Easy to carry – Compact size (approximately) height 4cm x length 13cm x width 4cm so you can play anytime and anywhere Recommended toys for boys and girls ages 7 and older who like superheroes, American comics, and pretend play.
