This tape is especially useful in places where needle holes have formed in the fabric during sewing and the seam needs extra protection from moisture.

💡 Usage tip: apply the tape to the seam from the inside of the fabric using heat and pressure. Before processing, always test the appropriate temperature on a small piece of fabric, as different waterproof materials may react differently to heat.
