This product is a full-body plush shark onesie designed for adults, made from ultra-soft polyester fleece. Unlike basic costumes, it delivers a detailed character look with expressive hood features, loose fit, and practical elements like pockets and mittens.

Wear the onesie by fastening the button-front closure for a secure fit. Hand wash only, lay flat to dry, and iron on low heat if needed to maintain fabric softness and detail integrity.

Crafted from 100% polyester plush fleece, quality is assured through careful fabric choice and construction. The button-front closure and reinforced cuffs enhance durability for extended wear.
