EDIT - THIS PEN IS AIR ERASABLE, NOT WATER ERASABLE - when I'd bought it, the description was air erasable, and that's what it is, not water erasable. I was worried that this would not live up to what it was claimed to - but, it is and does exactly what it's supposed to! It's a nice darkish shade of pink, almost a fuchsia, so it stands out well for many colors of fabric. It also disappears within about 30-60 minutes, so it's great for sewing - draw on the seam, and sew, and then it's gone! I've used it so far for cross-stitching - putting dots on the spots I'm going to cross-stitch immediately, like for some stitches I'd missed here-and-there in a counted cross-stitch project. Can't speak to how much ink the pen has or how long it will last, as I've only used it a few times and for small areas. But, so far very happy with it!

This only took three weeks and two days to arrive from China. TOTALLY worth the wait! I was worried it wouldn't work like advertised but it really does.No scrubbing, rubbing, or need to wash! I soaked it in water and watched it literally disappear! I am DEFINITELY buying more.I even snapped some pictures of it disappearing!Thank you, I love it!

Shipping was quick. My package arrived in less than 2 weeks. I bought a blue and a red one. The colors are bright and sharp. The inks get absorbed quickly and gets darker if you press harder into the cloth. I tested them on a piece of scrap Aida cloth and the ink from both pens disappeared within a minute of soaking in the water. The price is right too compared to the craft stores, and it comes with free shipping! Overall I'm very happy with this purchase.

Works great!
