Rental kitchens are where storage goes to be inadequate. You cannot put up a shelf, you cannot drill, and command strips peel the paint off on the way out. These two racks simply stick to the side of the fridge with magnets strong enough to hold around 2.7 kg each.
That is roughly a full set of spice jars per shelf, off the bench and in reach while you cook. The side of a fridge is dead space in almost every kitchen, and using it is the cheapest storage upgrade available to someone who is not allowed to change anything.
Each rack is about 25 cm long with a raised lip, so beyond spice jars it takes oils, a knife block's worth of utensils, cling film, or the collection of small bottles that otherwise colonise the bench. They are stainless steel rather than coated wire, so they wipe clean.
They will stick to anything ferrous, which in a rental often means the washing machine, a filing cabinet or a steel door. People buy them for the kitchen and then find a second use within a fortnight.
This suits anyone in a rental, a share house or a very small kitchen, and it is especially good for someone who has just moved and is still discovering where everything will not fit. Nothing about it is permanent, so it moves to the next place in a box.
One thing worth checking first: a few fridges have stainless or plastic exteriors that magnets will not grip. A fridge magnet already on their door is proof enough, and it is worth a glance before buying.
