Full-size wrenches don't fit where the small nuts live — inside chassis, behind terminal strips, around sensor fittings and connector jam nuts.
The Eclipse 900-217 is a 10-piece set of mini metric ignition-style combination wrenches sized for exactly that world: each slim, short-pattern wrench carries a closed (box) end on one side and an open end on the other, spanning closed-end sizes from 4 to 11 mm and open-end sizes from 4 to 10 mm.

The ignition-wrench pattern is the point.
Thin heads and short handles maneuver in clearances where standard combination wrenches physically cannot enter, and the dual-end design doubles the coverage of every piece: the box end grips all six flats for stubborn fasteners, the open end slips onto nuts with side access only. It's the set suited for work on electronic components and compact assemblies — instruments, small actuators, RF connectors, appliance internals, RC and hobby equipment.

Ten wrenches, one small pouch, pocket money price.
This is a stocking-stuffer-priced set that quietly solves a real recurring problem — and the kind of thing bench techs buy twice because the first set got adopted by a coworker.
