I thought I had checked that one. Description on GBO is confusing, as it doesn't state polycone cap, just polycap, and suggested cone cap below as"also fits your bottle"
Yeah; they could stand to improve their consistency/continuity regarding their descriptions.

Often looking at the extra images attached can help clarify things.

But, if you are ever not sure, give them a call and ask. I have always found them helpful and informative.
When I started stockpiling a couple of years ago; I made a shopping list, and a spreadsheet of all the ECF community vendor recommendations at the time, and did a comparison. GBO came out better (product+shipping) than all the rest. I don't bother checking any more.

Burch was a new one to me; so that was why I asked.
If you ever need plastic bottles in bulk; be sure to check out
DropperBottles. They only sell the plastic in units of 100, but if you send them an email or call them first, they will let you divvy up the 100 into various sizes (e.g. 20-5mL+20-15mL+30-30mL+30-60mL=100 bottles total), and all you do is pay the hundred count price for the most expensive size. I have not asked about mixing up bottle types (like some plastic bostons mixed with some unicorns). The freight is not gouging either.
They do offer glass as well; but they can't compete with GBO for selection (no polycone option

).
