There are only 2 companies in the USA that manufacture bocce balls.
The other suppliers with brands and products seen in general sports stores and online are distributors only and import balls mostly from China. A followup post will list those companies.
EPCO — E. Parrella Company, Inc.
36 Alder St
Medway, MA 02053
- EPCO emphasizes the manufacture of Bowling Balls. But has other product lines, billiard and pool balls and gear stick knobs and also bocce balls. Material used is called Partek. They are known for their Glow in the dark sets but these require a black light to get the effect.
These products are distributed by Paramount Industries – that has the same address as EPCO.
St. Pierre Manufacturing Corporation
317 East Mountain Street
Worcester, MA 01606
- StPierre is today the largest manufacturer of Pitching Horseshoes in the world. They also make a single line of bocce balls.
