If I end up doing it I'll ask in an hardware store but until then someone here might tell me it's actually not possible:
I'd like to get a coat hook for my SO's place, he doesn't have one but could likely use one, just doesn't know it
Since he's into climbing I thought about getting a climbing hold (shaped a bit like a hook) but was wondering if there's any way to put it on the wall without making a hole, so like, 'gluing' it (I can't find the US equivalent of the product I have in mind, a glue that holds up to 100kg/cm² (very roughly 220pounds/ 1/2 inch²) so the strength of it shouldn't be a problem).
But clearly, if I can't make a hole I don't want to leave a nasty trace or anything on the wall, so, does it come of? The website doesn't say anything about it, so if I make it a surprise* and he hates it he'll likely be quite unhappy if it ruins the wall (that would be a kind of painted wall(not)paper).
*When it will be our
place, not just his, and by asking/telling him before, the using a climbing hold will be the surprise.
