We bought a couple of 3M Command Brand Damage-Free hanging crochets (Product number 17201C for Canada) for hanging some dry-erase whiteboards. Immediately noticed its design is different than regular Velcro, so a closer look is needed on the material and catching mechanism. Let’s magnify the strip and check it out!
There are 6 strips total in a package which makes 3 double sided strips, still puzzling on why the odd number? It looks like all 6 strips are identical, including the pattern.

Here is a macro shot, notice the irregular pattern
Another angle view showing they are like tiny mushrooms!
Here is a magnified shot, check out the plastic mushrooms on a relatively smooth bottom.
