Methods vary: sticker-and-foil rollers (stick, peel the top layer, then roll foil across the sticker), print-to-tattoo-paper transfers applied with water, and marker-based drawing directly on skin, often used with stencils.
Removal guidance varies by kit but commonly includes washing with soap and water, using warm water, or peeling them off like stickers, depending on the tattoo type.
Some kits are battery-powered (often noted as "Battery: Required, Installed"), while at least one printer-style kit includes a USB charger for recharging.
Kits offer a range of styles and finishes, including pastel colors, metallic and shimmer foils, neon/glow and holographic effects, and standard multicolored or bold marker shades.
Kits are described as suitable for parties, festivals, slumber parties, birthdays, school breaks, playdates, and similar group or solo activities.
