The roll-on, and the missing ball
Updated

What the derived shelf is
Eleven glass Boston rounds, every one exactly 59.147 mL, all on 20-400, with 11 closures of which 7 are continuous thread and 4 are phenolic. Not one roll-on fitment, and only one size.
What the catalog actually holds
Under Bottles and Roller Balls: six glass roller ball bottles, an 8 mL clear, four at 10 mL in clear, amber, clear and frosted, and a 30 mL clear. Plus two white plastic roll-on bottles at 2 oz and 3 oz.
And the parts to complete them
Five roller ball fitments, in PP, in plastic over glass and in plastic over metal, and eight caps in black and white PP and in silver plastic over metal. That is a complete system, and the derivation does not place any of it on this shelf.
Which sizes a roll-on actually wants
8, 10 and 30 mL, which is exactly what those glass bottles are. A 59 mL roll-on is an unusual product; the 10 mL is the format this category sells.
Glass or metal ball
A metal ball rolls differently, feels colder and is usually the premium choice; a plastic or glass one is cheaper and lighter. Both are present, and for a high-alcohol formula the housing material matters as much as the ball.
A roll-on sidesteps the sprayer question
No pump, no dip tube, no spray pattern, and no 20-400 against 20-410 arithmetic. For a first fragrance product that is a genuinely simpler package.
It does not sidestep the alcohol
The ball housing and the cap are still polymer in contact with the formula, and a roll-on is carried in a bag and laid on its side. Seal and compatibility are the two things to test, over months.
