Color: Red Type: Mouthpiece It fits well and there's no worry about it coming out during use. It's comfortable to use, without feeling suffocated or the thickness bothering you. It's a very well-balanced mouthpiece. To make it, put it in boiling water for about 10-15 seconds, and when it stretches a little and becomes soft, put it on your teeth, adjust it, and lightly bite down to fit it perfectly! If it doesn't fit the first time, you can repeat the process 3 or 4 times to get a perfect fit! As a special bonus for a limited time, we're including a mouthpiece instruction manual and a mouthpiece case for first-time users. Anyone from beginners to advanced users can use it, and it can be used for various sports! When your bite is aligned, your physical ability and strength will increase, and you can expect improved sports performance!
