@quadmimi I've noticed the difference in straw thickness too! Perhaps the thicker formulas, like 613, have the wider straw. Hmmmm.....
So here is the cubby hole in my new shower.
The three plungers/dispensers to the left are the kind I have always gotten in the past five plus years. Tall.
The next four plungers/dispensers in the middle are the ones I got off eBay, where they said they were for the WEN 32-ounce bottles. That's as high as they go.
The single one at the far right is the plunger/dispenser that Chaz's team sent me. That is as far as it pops up! It is shorter than the eBay ones I got (thinking they were as tall as the ones on the left).
I emailed them about this and they said they would check their warehouse to see if they had any more of the taller ones.
As you can see, if you are used to using one full pump from the really tall ones (three on the left), but now you can only get the short ones (last one on the right), you have to pump 6-8 times for my short hair. Before all I did was one full pump from the tall plunger.
Not happy about this.
