The colours - black, blue and red work very well on all the fabrics I tried them on. The white is disappointing. That was what I really wanted - for drawing on dark fabric. Other reviewers warned that the white only shows up as it dries. This is true. But it means you can't see the lines as you draw them. You need to be very confident to draw without seeing! I used the blue eventually but it is not as successful as I had hoped. The pens were as described and they arrived on time. Did not contact the seller.

The white not to good on darker fabrics, you have to scribe a number of times I don't know if it will be still visible.B. H.

I really like these pens except for the white ones as I have found that they're a little hit or miss when using them, but the other colours are great.

The pens come empty so you need to put a refill in. But the refills are too short for the pen. You can see from the picture that when the cap is back on the refill doesn’t reach the end and the pen can’t be used. I tried it without the cap in some dark material and can confirm the other reviews which say that the white doesn’t work. I haven’t tried the others yet.

Great value for money drawing the lines a very fine line especially on fabrics .An excellent buy .
