This design element is often incorporated into face coverings intended for celebratory occasions, particularly those associated with the autumn season. Examples range from simple character portrayals to elaborate creature representations.
The inclusion of a dynamic mandible significantly enhances the realism and expressiveness of a disguise. This feature offers wearers the opportunity to create more immersive performances and interact more convincingly with others. Historically, such articulated elements were challenging to produce, but advancements in materials and manufacturing have made them more accessible and affordable.
