Review on 🥄 5 Ounce (0.67 Cup, 150 Milliliter) Coffee and Dry Goods Scoop - Ideal for Measuring Pet Food, Grains, Protein, Spices, and More (1-Pack) by Summer Zitzner

If you're looking for a custom 2/3 cup, this one will hold less. I googled to buy 2/3 cup and Revane pointed me to this measuring cup. I was disappointed that it doesn't measure 2/3 of a cup. So if you just want a scoop, you'll be happy. If you want the exact 2/3 cup measurement this isn't for you. I am very disappointed that I wasted my time and money. The seller explained that he never advertised this to even hold 2/3 cups. I hope my comments help others to look elsewhere.
