No rubber feet, or limiting device, so falls flat on a hard top desk.
With nothing to keep the signs propped open, then tend to fall flat at the slightest bump. They would be better if they had some rubber on their feet, or had a mechanical limiting setup, to keep them from opening all the way to flat. A small clip for the feet, or across the top opening, to hold it both open, and from opening further would be nice. The print is clear, and the message easy to get across. Both signs are decent thickness in plastic, My solution was to drill a tiny hole through both sides, and thread fishing string through, with knots on the end, then inside, to keep it from sliding out, then the other end, both inside and out. This limits the sign opening, but still lets it close without issue. That is the same solution I used for full sized signs as a night cleaner. For only costing nine dollars, to get two signs, this is a great deal for the desk personalization.
