I don't usually have children around my house, but for the the occasional times.... This is about as sturdy as a filing cabinet. Has decent 3-point lock... could be opened with a sledge hammer and crowbar but adequate to deny access to small fingers. http://www.walmart.com/ip/Stack-On-GCWB-10-5-DS-Sentinel-10-Gun-Security-Cabinet/14710131 FWIW...
Quite a bit more than $106. More like $1500. My son knows he's not allowed in my office without me, much less my locked office closet where the safe is closed and locked. Sometimes when I go into the safe, he tries to peek in my office door (or under it). It's funny to hear him trying to be quiet and sneak a peak. He knows there are all sorts of "cool" things in there (and the pellet rifle I let him practice with under my supervision).
Is that the pic in an ad. or is that your own gun safe ? i ask because i don't see any surrounding furniture of your office.
