The roll on, and what finishes one
On this page8
What is on the shelf
Glass roller ball bottles at 8 mL, 10 mL and 30 mL, in clear, amber and frosted. Five of the six sit on the grooming shelf, four of them inside the thin oil window as well as the aftershave one.
Three parts, not two
The bottle, the roller ball that presses into its neck, and the cap that goes over it. C&P lists the balls and the caps as their own items, which means a complete roll on is three line items on a purchase order rather than one.
The ball is a material decision
The balls come in polypropylene, in glass and in metal. Metal reads as the premium option and feels cold on skin, which is pleasant on a just-shaved face and is part of why aftershave suits this format.
Why it suits this craft
It doses a small amount of an expensive liquid with no waste and no overspray, it cannot leak in a bag the way a splash top can, and 10 mL is a price point a customer will try.
Beard oil can use it too
Four of these bottles fall inside the thin oil window. A 10 mL roll on is a travel size or a sampler for a beard oil that is normally sold at 30 mL in a dropper bottle.
One bottle has no stated fitment
Of the six, five publish the caps and balls that go with them and one does not. It is on the catalog and it is not on this shelf, because pairing it with a cap on a guess would be asserting a fit nobody has stated.
Label area at 10 mL
This is the smallest label in the whole craft. The four mandatory elements have to fit at the minimum type size on a bottle the width of a finger, which usually means a wrap label and a careful layout rather than a front and a back.
