Worth it !
Didn’t expect much but dang—these actually work great. I’ve been using them for quilting and even with dark fabric they show up fine. Heat makes the lines vanish fast. No mess, no hassle. Got tons of use outta just one pen too!

Suggestions to get the white pen to work
In spite of numerous reviews that the white pen didn’t function, I bought this set, and hoped for the best. My purple pen worked just fine, but the white didn’t. Sob. The white was just what I needed. I managed to make the purple one work for my project by using it on the back of the fabric, though dark on the front it’s a printed fabric, so quite light on the back. Ok. Problem solved. For the moment. Oh, and the purple disappeared like magic when ironed!I had received email from the seller about my purchase, wanting to know if everything was okay. I told him about the white pen. He suggested that I do several things to try to “wake up” the pen. None worked for this pen, but I thought I’d share his list of suggestions just in case they help someone else. Here goes:1) “Wake-up” scribble – On a scrap of dark fabric or paper, draw a continuous line or tight zig-zags for 20–30 seconds. You should see the ink turn from clear to opaque white after a short delay.2) Warm the tip – If it still won’t start, hold the metal tip between your fingers for 10–15 seconds or tap it lightly on the edge of a warm (not hot) mug. A tiny bit of warmth helps the gel flow.3) Store tip-down – Once the ink is flowing, keeping the pen upright (tip down) between sessions prevents air bubbles from creeping back in.

White pen does not work
The purple pen works, but the white pen was very troublesome. I used the white pen on denim and dark cotton, and both did not work. I could see faint lines when I wrote on a post it note, so it means the white ink is in there, but it does not work on fabric, which is what is advertised.Half stars for half working product.

A pen that really works!
They work amazingly! And they even include one refill for each pen!

Excellent for marking lines for quilting. The purple pen leaves a distinct line but irons away readily. I’ve been nervous in the past in case lines didn’t fully erase ( it happened to me) but these disappear fully and no sign of the lines returning.

Lila Farbe sehr gut sichtbar. Ist auch wirklich nach einmal bügeln restlos verschwunden. Weiße Farbe geht nur auf sehrdunkeln, schwarzem Stoff
