Constructed of an eco-friendly cotton, the Crube Scent Sponge is an accessory to help you be more versatile while fishing the Crube. Simply cut off 3/8 and slide this sponge into your Crube. The Scent Sponge can be used for a variety of applications. Soak it in your favorite scent and while your Crube is moving or sitting in the water, it will slowly release the scent to attract more fish. Also, you can use it to hold your glass rattle in place, giving your Crube more sound to attract fish. Engineered to fit snug inside the Crube, The Scent Sponge is a must have in your tackle box.
