Set of 2 O-shaped magnetic hooks for GADIS shades, NMT-F11 x 3 * Weight capacity: 2kg (when using 2 hooks) * Suitable for shades up to 100cm x 300cm * Strong hold with the combined effect of magnets and non-slip sheets! I bought these to attach shades, but I didn't end up using them. It looks like it's going to be hot this year, so please give them a try.
