Thank you for viewing! This is a magnet sheet the same size and magnetic strength as the "waterworks bureau advertisement magnets" often found in mailboxes. There is no design (advertisement) on it, just a simple plain surface. 【Product Details】 • Size: 9.0cm x 5.5cm (approximately the same size as a standard business card) • Color: Front: Black / Back: Black (magnet surface) • Uses: Perfect for attaching to the back of handmade items, holding memos on a whiteboard, or as a DIY material. 【Condition and Notes】 • The original advertisement paper has been peeled off and processed. • We will clean off any stickiness as much as possible before shipping, but slight "residue from the paper removal" may remain. • Please consider this product assuming it will be used for handmade projects or as a backing. • We kindly ask that those who are concerned about minor imperfections or are looking for a perfect, new product refrain from purchasing. Instant purchase is welcome!
