We keep it simple: give artists the best, don’t charge 'em stupid money. TIGER SPIT Round Magnum cartridges are built with semi-textured needles — not fully polished, not overly rough — just enough grip to hold ink and lay it in smooth, with less trauma and better flow control.
Perfect for black & grey, soft blends, color packing, and whip shading when you need smooth transitions but still want saturation that sticks.
These round mags are precise, pre-sterile, and built to run. Snap 'em in, hit your blends, clean up, and move on.

Use it once. Trash it. Keep your shop tight. No sketchy re-use, no cutting corners — ever.
Some needles chew skin. Some slide off too smooth. These sit right in the middle — semi-textured for grip, flow, and control. That’s the TIGER SPIT™ way: gear that works hard, priced right, and made for real artists.
