Here is a medium size waterproof top tube Bento Box from Sunlite, a well known manufacturer of high quality bicycle accessories. This Bento Box features 100% waterproof construction and a 52 cubic inch main compartment.

Attaching the Bento Box is a snap with its three hook & loop straps. The dimensions are a copious 6-1/8" x 2-3/4" x 3-1/8.

The term "Bento box" originated as a lacquered Japanese lunch container, and the often artistic creations held within. Today's Bento box has been redefined by cyclists to designate a small frame-mounted container just about large enough to hold the rider's lunch and an energy drink.
