Clingy thingies are made with a special cling technology. They are not sticky to the touch, yet they stick to smooth surfaces such as doors, glass, whiteboards, file cabinets, and more. Can be easily removed. You can even use water to rinse lint or dirt off the back surface. Clingy thingies can be used again and again without leaving any mess or residue. They also feature a write-on/wipe-off surface, perfect for notes, labeling, and reminders. Does not stick well to textured surfaces and is not recommended in areas exposed to extreme heat or direct sunlight.
