I think this product is excellent. I am just starting out tattooing, but learned a lot from a friend over the years of him doing ink on me, so I know what I am doing. I love this product and would recommend it to anyone.The item is great all my tat machines were ten wrap coils which works for shade or line and great for magnum! Shipping was fast and on time. The best i have had from Tmart! Thanks a lot.
