100-Piece Silver Fabric Pen Refills – 5.11" Fabric Markers for Sewing Erasable Ink | Safe for Most Fabrics | 0.03 Inches Fine Tip for Quilting, Tailoring, and Crafting - Great as Valentines Day Gift

Works great for marking vinyl and dark fabric.

I used to buy the silver pens from Tandy, but they are expensive for what you get from them. (I've purchased some that only have 1" of ink in them.) I will be buying these from now on. Like another reviewer says, they fit in the Tandy silver pen. The ink cleans off just as easy. Plus you get 100 refills for the price of two pens from Tandy. So if some of the 100 dry up before you get to use them, they will still be a far better deal. Now I want to find a solid pen case to use with these refills, but for now my old Tandy pen case will work.

Great water based pens. I use them on leather and vinyl and they wash off great with a soap/water mix. They do tend to use up fairly quickly but there’s a lot in one pack so it’ll last you a fairly long time. Just make sure to wash it off at least after 2-3 days as sometimes it’s a little more difficult to wash the pen mark off

These pens work fantastic on faux leather. I have had mixed results removing the marks made but I primarily use them for tracing pattern pieces to cut out so it isn't an issue. The color shows up great on dark and light colored material. Extremely easy to use. They are strong enough to be able to use just the refill and feel sturdy.

I found these pens through leatherwork and now I use these pens for many things like making patterns on paper then drawing the pattern onto leather. They mark easily on wood, and cloth as well. Crafters will love these! Don’t use on veg-tan leather if you want to erase the marks. Buy several because the ink goes fast since it flows so well.

I like these pens because they show up well on most fabrics. The silver shows up nicely. I stay on the outer edges when marking because these don’t out with heat.

This silver refill ink was great for my felt crafts and showed up the best on all colors. —That is, until I tried to remove it with a heated iron. I have had no problem with any other color thermal ink before so I gradually increased the heat to the highest setting. Still no-go. The silvery color disappears leaving a black line behind. I contacted the seller to see if there was some trick I was missing but was directed to increase the heat setting. Been there, done that. They promptly refunded my purchase. Unfortunately, I had completed an order for 15 hand embroidered Christmas ornaments and all of them had black ink left behind as a guide for the embroidery design. Amazingly, my Aunt who was the customer (yay!) actually liked the effect on the poinsettia leaves so I wasn’t out time and materials (wool felt + embroidery thread)! I still cried because I pride myself on my attention to detail. ** Please note: This issue was limited to the silver color ink ONLY. All other inks functioned as advertised. Very responsive seller. They apologized for the difficulty and refunded the purchase lightening-fast. They even reached out to me again later to make sure the problem had been resolved to my satisfaction. Excellent customer care! I will order from this seller again—I’ll just make sure it is for any other color than silver. 😉

Work great on vinyl, haven't tried them on leather yet. Price is great for what you get. Nice clean lines. As a side note: These are just the refills. If you don't have say a Tandy pen that these will work with, you can go to the Dollar store and get some of the cheep Bic stick pens, and these will slide in them. Then you will have a proper pen to hold on to.
