With the Vitamix - 2x225ml cups + blade base for the A2500/A3500, you have small mixing cups and an extra blade for your Vitamix A2500 or A3500 at your disposal. A small mixing cup is useful when you want to finely mix herbs or nuts. You can also use the mixing cup to make a delicious salsa. Whatever you use them for, you can immediately store your dish in the mixing cup thanks to the included lids. Nice!
