WedFeir Heat Erasable Fabric Marking Pens with 28 Refills for Tailors Sewing, and Quilting Dressmaking, 4 Colors Heat Erase Pens of Fabrics.

Funcionan bien pero se acaban muy rápido. Si hay que marcar varias veces. Pero en total estoy muy contenta con los marcadores

I have been using these marking pens for over a half year now. They are simply perfect for marking up a variety of fabrics...cottons, blends, minky, sherpa etc. The inks do not smudge and with four different colours, there is always one that stands outs. When using on minky and sherpa (fabrics that cannot be ironed) I simply use my steamer to remove the markings. Works like a charm. Will definitely purchase these again, but that may be a while, as there are so many refills. Good problem to have!

There are no assembly instructions that come with the product, so I had to fiddle with it before I got it working. I felt I had to write this review to guide others. The problem is in the wording of the instructions where the writer assumes you, the consumer, is skilled at assembling and understands how things work. Not so, even if it appears to be common sense. After fiddling with it, it all worked perfectly fine. It’s actually simple, but I should not have had to spend time figuring out how to get it done. So here it is in photos. I hope it helps you. It helps if you identify the parts first--see Photo 1.1. First remove the protective cap.2. Then unscrew the metal tip. This is the part of assembly that wasn’t described by the seller. Set aside the tip to replace later.3. Then take one ink refill and remove and discard the plastic tip covering the point end.4. Slide it through the hole from where you unscrewed the metal tip (NOT THE CAP END!). The point end should be jutting out once the bottom of the refill tube reaches the cap end—no need to force it through the tube. DO NOT ATTEMPT TO REMOVE THE CAP END. It stays in place.5. Replace the metal tip by screwing it back in. You’re now ready to use the pen. Always replace the protective cap to prevent the ink from drying out.6. MARKINGS: The 1st row of broken lines shows markings on cotton knit. The 2nd row shows how instantly the mark disappears by applying heat from a flatiron. The 3rd row shows white markings on extra thick wool. Wait a bit before the white lines appear as the lines won’t show instantly like the other ink colors.

These pens are perfect for fabric, dispersing under a warm iron

I was SO hesitant seeing how bright the red was on the fabric, but the ink instantly disappeared with the iron barely touching it. The 1st photo shows the red ink. The 2nd photo after I've sewn the fabric and ironed.The red, black and blue are all absolutely incredible. The white goes on very, very light to almost not working.I still have this a 5-star because value for even 21 of 28 of these refills is an insane deal for such a great product.
