Hey Dave, got mine & I wanted to share something with your customers & maybe you.
They are different from the last batch. This latest batch hold even MORE
juice!

I'm getting @ 30 to 35 drops in these.
The only drawback is,if you are one that removes the white plug & put's a regular tip in, you'll have to cut off about a 1/4". Other wise they won't hit & you'll get a mouth full of
juice. It's like putting a straw right in the
juice. I cut mine off even with the vents, so that only leaves 3/16" of a lip on the tip.
Now the only problem with that is some tips don't fit as snug as others. So I would make sure I had a tight fitting tip B4 I started cutting on them.
I hope this helps. I was pulling my hair out there for a couple hours before I figured it out. I had opened my 3rd carto

& was about to send them back.
There's a full 1/4" more stuffing in the new shipment of carto's. The 1rst batch I got had a 1/2" of clearance to the stuffing,these only a 1/4".
It's all GOOD!
And Dave, as always thanks for your impeccable service & fine line of products.
Cheers,
NB
