Four leaves, one of them a blade
On this page11
Binding clips are the bulkiest leaf
A clip is roughly a centimeter across with a sprung jaw, and a working set runs to several dozen. They do not nest, so they occupy more volume than their mass suggests.
Quilt pins are long for a pin
Longer and heavier than a dressmaking pin because they pass through three layers plus batting. Which makes them a length problem as well as a sharps problem.
Template parts are flat and want to stay in order
A template, a corner guide or a locking nut for a ruler. Flat things in a deep jar have to be shaken out, which is the wrong action for anything sharing the jar with a pin.
And the rotary blade is the one that changes the requirement
A 45 mm rotary blade is a disc with a continuous cutting edge. Used blades accumulate because they stop cutting cleanly long before they stop cutting.
Which is the practical reason a used blade jar exists at all
The blade has to go somewhere between coming off the cutter and being disposed of, and loose in a drawer is the answer that causes the problem.
Nothing on this shelf is recorded as child resistant
No closure in this group carries that classification in the catalog. Which is a statement about the record and about this shelf, and it is the whole of what these pages say on the subject.
And nothing here is guidance about handling a blade
That is not a packaging question and this is a packaging catalog. The pages describe what is on the shelf and decline the rest.
The four leaves do split cleanly on one axis
Clips and template parts want a wide shallow floor they can be spread across. Pins and blades want a container that closes properly and is not reached into blind.
Which argues for more than one container, as it usually does here
And the shelf is well supplied in the band that suits both: the median capacity is 118 mL, and 157 of the 181 containers are jars rather than bottles or tubes.
None of the four is within part 1610
The standard classifies the flammability of clothing textiles. A clip, a pin, a blade and a template are not textiles and nothing on these pages says the standard reaches them.
