Two sizes avaiable:

1. Lotion pump with a 28/410 neck. This pump fits all of our amber glass bottles and our plastic amber 500ml bottle.

2. Lotion pumps available to fit our 250ml clear PET bottle.
Black with a 24/415 neck.
White with a 24/410 neck.

For your interest:
All caps have two measurements to show what bottle they will fit.
Here, 24 and 28 refer to the diameter of the neck of the bottle; 415 and 410 refer to the length of the neck.

If a 24-neck bottle has a short neck, it will need a 24/410 cap.
If it has a long neck, either a 410 or 415 cap will fit, but the 410 won't come right down to the shoulder.

A 415 neck won't fit a 410 bottle. It will be too long and won't screw on properly.
