I did a quick look at my usual go-to bottle sites, and can hit
some features, but not
all. Wide mouth seems to be the most difficult (especially LDPE; PET is a
little more common).
What are the important (to
you) features? Wide mouth? LDPE material? Size/volume? Quantity? Shape (Boston round, unicorn/gorilla, cylinder, etc.), tip type?
What, ideally, would you want to order right now (sizes, and quantities)(and, forgetting about vendor limitations for the moment)?
Knowing what are "must haves," and what are "it would be nice to have," and any "I don't really care;" may help us direct you to best possible choices.
Edit to add:
I don't know if you are already aware; but DropperBottle will mix and match on orders. They
do have to total 100 units; but they can consist of multiple sizes (e.g. 50ea./30mL, 25ea./60mL, 25ea./120mL). You just pay for 100 of whatever the largest size is. You end up paying a little more per bottle, but you get the convenience of mixed sizes.
Just shoot them an email of what you would
like to order and they will let you know if they are able to do it.
