I’ve had a similar measuring cup like this for a couple years now. My mother-in-law gave it to me about 6-7 years ago. However, mine is pure plastic and the edges show their age through the wear and tear.
I decided to get the Wonder Plunger Measuring Cup listed on Think Geek. The feel of the plastic feels like silicon. I think this one will definitely last longer than my yellow one.
Here are some features (from the Think Geek website):
Plunger-style measuring cup
Best for wet and sticky ingredients
Pushes all ingredients out without losing any
Holds 1 cup, but measures in fluid ounces, milliliters, teaspoons, tablespoons and cups
This is one of those necessary tools for the kitchen. If you are having a hard time finding a gift for your personal chef, I recommend this tool.
