Query: useful purchase

bought this product for my boyfriend who bikes to work everyday. This compact stow away pouch fits his house keys, work badge, glasses with its bulky case, wallet, and cell phone. It fits securely on the bike, but he likes to strap it on the front of the bike just in case the velcro straps were not strapped on properly.
