Everyday carry toolset

The Cholemy QIN3990 bundle supplies twelve credit-card-sized multitools, each milled from stainless steel and fitted with its own leather sleeve. Each card measures 3.15 x 2.1 inches and packs 46 functions into a profile thin enough for any wallet slot. The set covers black, red and gold finishes for quick visual sorting.

Build integration

At 8 x 5.3 cm the cards occupy a single card pocket, freeing belt space that a traditional multi-tool would consume. Stainless steel construction resists corrosion when carried against coins or keys. No additional organiser is required because every unit ships pre-cased in leather.

Leather sleeves add readiness

Individual cases protect edges and prevent the pointed features from snagging fabric or scratching screens. The sleeves also let owners distribute tools across a go-bag, desk drawer and vehicle glove box without loose metal rattling. Colour coding on the card faces speeds identification when multiple people share the pack.

Questions about this item

Does the stainless steel card bend or wear out after repeated prying and tightening?

The cards are made from stainless steel, which resists bending and corrosion during everyday prying, tightening and cutting tasks.

Do the edges stay smooth or become sharp enough to damage pockets after all-day carry?

Each card ships inside its own leather case, so the metal edges never contact fabric or skin while carried in a wallet or pocket.

What must I already have to use the 46 functions — does it need a separate handle or power source?

No extra handle, battery or tool is required; the card itself contains every wrench, driver, cutter and opener built into its 3.15 x 2.1 in frame.
