Salt Water Etching Kit — for the love of etching & texture

Turn line, letter, and texture into metal—cleanly, safely, and with gorgeous control. This kit is built for makers who want crisp, repeatable salt-water etches (no acids), USB-C-powered convenience, and big, real metal to play on.

Made to order: please allow ~2 weeks for production before your order ships.

Why this kit rocks

• Clean, even etch: large 18-gauge copper anode stays flat and distributes current evenly for tidy edges.

• Real canvas: a full 6″×6″ 18-gauge copper sheet to explore handwriting, stencils, textures, and bold linework.

• Simple power: 5V USB-C. Supply your own power cube.

• Maker-forward tooling: paint-marker resist, electrical tape dams, a pre-wired clip lead, and a tiny Hardware Pack for hang holes and clever fixturing.

• Studio-ready: PDF (CORE) manual or a full-color booklet (PRO).
