The set of gun wax allows for easy sealing and is perfect for invitation and decoration applications. Easy for beginners. How to Use: 1. Insert the gun wax from the back of the main unit, then insert the plug into the outlet, and wait for 5 minutes until the wax is fully dissolved. 2. Pull the trigger slowly while feeling the hand and pour the appropriate amount of wax to the desired seal. 3. Wait for a breath before pressing the stamp. The time may vary depending on the season, but please take about 20 seconds. 4. Gently press the stamp before the wax completely dry. Note: If the stamp is pressed in a warm state, the wax may not peel. If you want to stamp it continuously or during the summer, please cool the stamp with an ice pack.
