Using this Mirage snorkel set is easy. First, put on the mask. Make sure the high - grade silicone skirt fits snugly around your face to prevent water from leaking in. Then, place the snorkel in your mouth, using the silicone mouthpiece. The splash guard on the snorkel will stop water from splashing in. When you're done snorkelling, rinse the mask and snorkel with fresh water to remove any salt or sand. Let them dry in a cool, shaded place. Don't expose them to direct sunlight for too long as it can damage the silicone. Check the silicone parts regularly for any signs of wear and tear. If you notice any issues, it might be time to replace the set. Enjoy your snorkelling adventures with this great set!
