Works good. Easy to use with instructions found in description. The box it self didn't come with instructions, had to read them of the item listing. Not sure if its easier or better than rinsing the needle as they are expensive but does what it says.

These things are awesome. They are a large enough surface area to get some good designs in, the material soaks up ink pretty well, I do recommend washing the pad before you tattoo it because it helps the needle glide across the surface better and makes sure there are no chemicals or contaminants on the surface. Overall, these are perfect for the price.

I did a re-order thinking I would be safe. This is not at all like the list batch. Ink does not wipe off. Would not recommend.
