Hummingbird made a number of high quality paddleballs. Oversized and thick paddles, with replaceable rubber strings. The paddles were laminated plywood, 3/8" thick and 11 inches long. Even tools for re-stringing new rubber balls.
Pictured here is a later Oh!Zone Paddle. Notice the paddle itself is natural finished wood, but a large sticker covers the front surface. Neon paint easily cracked and chipped, which was a problem with painted neon items.
