We have a few of these. One is never enough is it? Ours are called Useful Boxes and there's one on top of the fridge freezer, one in the baking cupboard, plus the middle drawer.
They do have a trend of their own - useful box on the fridge has screwdrivers, tape measures, (note intention plurals) a smoke alarm, cable ties, picture hanging kits, a freezer bag with glue products in (including Pritt sticks, oddly) wallplugs (yellow only), Raspberry Pi box, old phones, a Wallace & Gromit stationery pack free from Kingsmill, a paintbrush (looks elderly but unused), pack of antibac wipes (unopened).
Useful box in the cupboard tends more towards name labels, batteries of every type and size imaginable, notebooks that came free with Cosmopolitan ten years ago, a pack of stick on lights (for understairs cupboards and the like) with one gone from the pack, windscreen repair kit (used), extra long safety matches, Command hanging strips, party balloons, a waterproof padlock (still in pack), multicoloured elastic bands, a pack of playing cards, some silicone, mysterious items in static proof envelopes, the ubiquitous empty glasses case and some sunglasses.
Both contain small scented candles. There's no medicines, light bulbs, sewing items, greetings cards or miscellaneous chargers or cables because I already have boxes for those... 
The middle drawer in the kitchen is also a magnet for otherwise homeless items, but I'm going to have a clear out of that. It should just be freezer and sandwich bags in every size and denomination under the sun; rolls of foil, cling film and baking paper; those foil dishes for sticking your leftovers in the freezer and no bits, like sticky tape rolls, pamphlets about places to go and yet more pairs of sunglasses...
