Rawlplug Multicolour Plastic Wall plug, Pack of 144

Straight up the worst design of wall plug ever. The plug is designed to split apart right along its length instead of the typical action where the part where shank of the screw runs through is not intended to split, and only the last part at the end of the screw in the wall opens up and wedges, so these are useless in plaster, as they open up right on the surface of the wall, and in anything other than solid brickwork they simply do not work. Add in the fact that they are very short, which just makes them even worse. I'll be throwing these away and buying another manufacturer's product. I had to resort to hand-cutting traditional wooden plugs and hammering them into the wall.
