The Lilipad Notepad and Liliput Pen combination from Troika is the perfect addition to a toolbox. It's also good for handbags and back pockets, but its true home is the garage or garden shed.

But why? Well to start with, it's small: the notebook measures just 105mm x 75mm (A7). Also, it's robust. The hard eggyolk-yellow cover is tactile, with rounded corners, and has a ruler marked in centimetres and millimetres debossed near the spine. A sturdy elasticated grey loop keeps the notebook closed, and there's a useful fabric page marker, also in grey. The inside back cover features an expandable pocket. It contains 128 pages of FSC-certified white paper, perforated for easy removal, with a dotgrid layout so it doesn't matter if you want to write something, sketch something or draw a diagram.

Just 82mm long, it features slotted and Phillips screwdrivers, a capacitive stylus and a ruler marked in inches as well as centimetres and millimetres. Oh, and it's a ballpoint too, with a black refill. A sturdy pocket clip means you can attach it to your shirt if you don't want to house it in the pen loop that comes with the Lilipad.
