The Heat Erasable Pens have received mixed reviews from customers. Some users found the pens easy to use, mentioning that they can be used on various fabrics including rough textured linen and craft felt sheets. However, some users experienced issues with the ink reappearing at lower temperatures, with one user reporting that the ink reappeared on a quilt left in a cold car overnight. Additionally, some users had difficulty getting the white pen to work and experienced challenges removing the ink if left on the fabric for too long. There were also conflicting opinions on whether the ink would run and stain when handwashed instead of heated. Overall, while these pens are versatile and convenient for sewing and quilting projects, users should be cautious of potential reappearing ink and difficulty in using certain pen colors.
