Nothing here is a purpose-made music product. Said plainly, because it changes what to buy.

Reed storage

Cane reeds, flat, stored in a controlled humidity, separated so they do not rest against each other. A reed case does all three and this catalog does none of them.

Where a jar genuinely helps

Bulk storage of unopened reeds in a band room, with a humidity pack. A wide straight sided jar with a lined lid holds the environment even if it does not hold the reeds flat.

Rosin storage

A brittle cake that sheds powder. It wants a container deeper than the cake, with a lid, that will not shatter when the case is dropped.

Which rules out glass

119 glass containers here and none of them belongs in an instrument case. A PET or PP jar is the right substitute for the missing tin.

String storage

Sealed is the requirement, and uncoiled or loosely coiled is the second one. The packet the strings came in is better than anything here until it is opened.

And then a lined jar is reasonable

11 liners and sealing discs. A spare set in a sealed jar outlasts one in a case pocket by a long way.

Mouthpiece storage

Separation and padding, not sealing. A mouthpiece chipped on its tip rail is scrap, and the chip happens against another hard object.

Which a jar does badly

Two mouthpieces in one jar is two hard objects in a hard container. This is the leaf where a purpose-made pouch or a padded box is not a luxury.

A case that goes outdoors, gets cold, gets warm, and gets dropped. Everything in it is subject to that and nothing here is designed around it.

The honest recommendation

Buy purpose-made for the player-facing storage, and buy from us for bulk, for a band room cupboard and for a repair bench.

The Davis Pack Supply catalog, measured 19 October 2026. The instrument care shelf is 1,026 rows: 525 containers and 501 closures. 5 mL to 500 mL with a median of 118; 30 containers at 15 mL or under, 100 at 30 or under, 207 at 60 or under, 390 at 120 or under. 266 PET, 119 glass, 78 PP, 62 HDPE, and no steel or tins at all. 287 bottles, 224 jars, 12 tubs and pails, 2 tubes. 147 clear, 112 white, 82 amber, 51 blue, 45 natural, 37 black. Closures: 345 continuous thread, 43 dropper assemblies, 27 dome lids, 19 lug and twist, 16 flip top, 14 phenolic, 11 liners and sealing discs, 6 dropper tips and caps, 6 round tubs. Necks: 96 at 20-410, 59 at 24-410, 56 at 89-400, 56 at 70-400.

The archetype behind this shelf is store-small-dry: 15 to 500 mL, wide mouth, PP and PET and glass, cold, solid, chunky, scooped, with "small dry parts, wide mouth to get fingers in, clear so you can see what is inside" as its stated reason. It describes the four dry leaves well and the two lubricants not at all, and the shelf is 287 bottles to 224 jars against a wide-mouth rule.

Written from 21 CFR 172.878 and from the catalog as it stood on 19 October 2026. Nothing here says a food-contact regulation applies to an instrument lubricant; 172.878 is cited as the published specification for white mineral oil, which is the benchmark a manufacturer can either meet or not. The other four leaves have no governing regulation and this property says so rather than borrowing one.
