Loose ring straight

Straight mouthpiece:

• A straight mouthpiece consists of 1 piece and gives pressure on the tongue, layers and lips.
• The shape and thickness of the mouthpiece determine where the pressure will be in the mouth.
• A straight mouthpiece with a tongue port gives more pressure on the layers and keeps the tongue free.
• The straighter and thicker the mouthpiece, the more pressure on the tongue.
