Review on 🎄 Longten Christmas Window Static Stickers - Santa Claus, Snowman, Deer, Snowflake - Removable Vinyl Christmas Tree DIY Decal Sticker for Wall, Window, Door - Mural Cling for Showcase by Katie Jefferson

These aren't "hooks" at all. These are stickers with strong adhesives that make them difficult to reuse as the edges are difficult to lift off without damaging them and leave adhesive residue that regular window cleaner cannot remove. Acetone can help clean the glass. The decorations on it are very nice (as advertised). If you don't use them over and over again because the windows "stick" and you have a strong enough cleaner to remove adhesive residue, I would recommend these decorative stickers. Personally, I'd rather use "stickies" because they're more efficient in every way.
