Do I read this correctly?
AI can't get the link to work unfortunately, but I believe the 1.25" would refer to the diameter of the scoop itself rather than the finished product.
Edited to add: now that I'm pondering, I think I may be wrong. 1.25" is a somewhat large diameter for the scoop- I think that size would hold more than .33 ounces. Hopefully someone else will come along and clarify.
Looks like it is similar to a " # 100 disher ", as a reference.
