M&G iErase III Friction & Heat Erasable Retractable Pens (Black)

I was highly suspect about the claims of heat dissipating the marks, but it does.Excellent pen for anyone requiring to make temporary marks on fabric.

only work when they want to. refills needed after very little use.

Only one out of the pens actually worked and that dried up very quickly. I would not buy them again

These are extremely handy especially with measuring or free motion embroidery. Wouldn't be without them

Would definitely buy more
