BRIGHTFROM Universal Dispensing Pump, Perfect for Shampoo & Conditioner 1 L (33.8 OZ) - Fits Most Bottles or Any Refillable Bottles from 12oz to 33.8oz with 28/410 Neck Size, Black (Pack of 2)

Love the color because the redken original lid is black, it pumps with no issues, it's perfect size, amazing product.

I needed a pump for shampoo that was hard to squeeze out from the bottle, so I took a chance on these. They work really well. While they were too tall, I was able to trim them down to the bottle height with scissors. Highly recommend and they are a decent price.

Works in Dr. Bronner's standard bottle. Without trimming, it'd need a slight bend at the bottom to curl to an edge against the bottle's bottom corner. Could be trimmed, but I prefer the to-the-last-drop style.

Fits the 33oz Redken bottles perfectly

Product had a great price point but unfortunately it didn’t meet my needs. It was too big for what I intended it for.

Love these 1”l pumps. Makes life much easier!

Fit perfectly on liter shampoo bottles that I have of all different brands so I didn’t have to try to get the product out manually.

I buy the 1-liter American Crew shampoo and conditioner because it's less expensive than the smaller bottles, but they're awkward to use because of their size and they're slippery in the shower. These pumps make it a lot easier to use, and provide a measured amount without worrying about dropping the bottle. The tube is the exact right length for the bottles and I've had them for well over a year without issue.

These don’t fit the bed head shampoo & conditioner bottles. I read somewhere that an 28/410 neck would work but it’s not correct. Overall look like decent pumps if they were the right size.
