Using your Mjolnir hammer is easy! Just press the button on the handle, and it will light up and make thunder sound effects like in the movie. To display it, use the included stand and show it off in your Marvel Legends collection. Remember, this product has small parts, so keep it away from children under 3 years old. You'll need to buy three 1.5V AA alkaline batteries separately to make it work. Also, if you're sensitive to LED lights or have epilepsy, be careful when using the lights on the hammer. To maintain it, keep it in a dry place and avoid dropping it to prevent any damage to the lights or the sculpted details.
