Fill a large saucepan with water. Bring the water to a simmer. Add the vinegar, then carefully add the eggs to the simmering water. Cook for 6 minutes.
Remove the eggs from the water and quickly transfer them to a bowl of ice water to stop them from cooking further. Let them cool completely in the water for at least 10 minutes.
While the eggs are cooling, in a bowl or container, make the marinade by combining the soy sauce, water, honey, garlic, green and red peppers, green onions, and sesame seeds. Mix well until everything is combined.
Remove the eggs from the ice bath. One at a time, gently tap each egg all over, cracking the shell. Peel off a small portion of the shell, then continue to remove the rest by hand, or run a small spoon under the shell to remove it from the egg.
Place the peeled eggs in the marinade, making sure they are covered completely by the mixture. Cover the container and let the eggs marinate in the fridge for at least 2 hours or overnight before serving as desired.
