We have been looking for awhile now for a nice set of smaller screwdrivers. Our one keychain mini screwdriver was lost only a few days after we bought it! We have three people in our home that wear glasses and two are children. At least once a week one of the two needs their glasses tightened! These are also excellent for any other small projects or appliances that need a smaller size driver. I do love the case these come in as they are easy to store neatly and find when needed! Definitely a must have for an household, office or tool box! Great gift!
