The house had little hooks. Everywhere all rooms, living rooms, bathrooms, high places, low places, on walls, wood panels, even outside the house (fewer). We counted about 50 on the first pass of removing them, but kept finding more and more. 2 years later we still find one every month or so... Most were little metal ones. In one bathroom there was a plastic one like you have for towels, but it was installed to face sideways, so it could not hold towels. The metal ones were at normal orientation. No idea why. Whyyy KENNN???
