Non-Aramith items:
The balls shown on this page are not Aramith (or Brunswick). Aramith has never used these fonts or bright whites.
If the balls appear to be in good/excellent condition but have a dull or matte finish, or are very white, they're NOT Aramith. If the balls have scratches on the colors and it appears to be white underneath, they're not Aramith. Most economy balls are literally painted cue balls. The five Aramith models mentioned on this site all have "through body" color.
There are other balls with the same or similar font to Aramith Standard/Premier, and Super Pro, but check them closely. Sometimes there are subtle differences.
What's the value of generic/economy/budget balls? Online sellers will deliver a set of brand new balls for as little as $18 - inclusive of shipping. Walmart has sets for $30.
