There are three Pick A Brick containers – The 950ml tumbler, 475ml tumbler and 30ml lid. I have measured the volume of these containers using a 0.1g scale and water; I have high confidence in the measurements. Other measurements have been taken with callipers and rulers; I have lower levels of confidence in those numbers.

The lid’s stud (where you can store LEGO if you’re particularly cunning) is 48mm diameter and approximately 16mm deep – six studs in diameter by two studs deep. This means you can’t fit something six studs wide (48mm) into it, because LEGO bricks aren’t 0mm tall or long. You might be able to store one 1×6 plate if you jammed it in, as plastic objects are plastic (bendy).

The 475ml tumbler has a profile matching that of the 950ml tumber, cut off at the bottom. They share an opening of over 100mm. They both have an indentation that matches that in the lid, allowing stacking. The displacement of the indentation of the base is 55mm wide and has three strengthening piers projecting into the interior of the base.

The length of the interior wall top-to-bottom depth of the 475ml tumbler is 76mm; it can hold 1675 1×1 round plates. The top-to-bottom depth of the 950ml tumbler is 170mm.
