Generally speaking, thumbtacks are always easy to pin on the board ,but they are hard to be pulled out; what's more, it might hurt your nails when doing so.
Universal Thumbtack is composed of the metal part and the rubber part. When the two parts are combined together, it would be easy to pin it on the board for one of the radius of the circle is made by metal. On the other hand, it would also be simple to be removed owing to the rubber part. All you have to do is put your index finger into the semicircle (the one without metal brace), then pulling out thumbtacks will not be annoying anymore!
