You are looking at Audio Origami PTA Plastic Isolation Spike Feet, with double-sided sticky pads.
These are ideal for Hi-fi separates (e.g. CD players, amplifiers, tuners, streamers, turntables etc).
This item is manufactured by Johnny of Audio Origami.
Due to the hollow internally braced lattice structure (85% hollow), these Isolation Spike Feet will give superior isolation, as opposed to solid structure examples, have great strength and (due to having soft plastic at the tip) will protect delicate surfaces.
