It will be shipped in simple packaging via Compact Delivery.

(Note: ① Do not use a charging head that exceeds 2A to charge the product, as the battery may generate heat. ② The cooling plate dissipates a small amount of heat during cooling, and heat is released from the neck heat dissipation holes. It is not abnormal for slight heat to be generated during use.) ※ Scheduled to ship on weekdays.
