After trying this product, my t-shirt designs have never looked better. The alignment guide is user-friendly and makes it easy for me to create symmetrical designs on any shirt.The package comes with four different sizes, which is perfect for designing for both adults and children. My only con would be that the guide is made of plastic, which is not as durable as metal. However, with proper care, this product will last a long time and help you create flawless designs..See full review
