Original red 3.1 were bigger and the current red are smaller and were gold colored.
Guess I’ll use them & try again to get correct ones next time.

Lactona XS 3.1MM INTERDENTAL BRUSHES-RED
These are extremely helpful in dislodging stubborn food items lodged between one's teeth, especially when dental floss can't do that alone. I've been using this product for five years. I place the interdental brush in a brush handle, which measures about 7 1/4 inches. These interdental brushes are a superb product!
