 This BYTAL™ includes a level and magnet, and a 40 cm tape measure extends from a space the size of a fingernail at the end.
 The tape measure is made of stainless steel so it won't rust.
 There are two different types of levels. The coin level can quickly determine the approximate xy level.
 At the same time, the tubular level allows for more precise and accurate checking.
 It can be used for various tasks such as installing shelves, adjusting wall-mounted TVs, etc.
 Attached to iron materials with a powerful neodymium magnet, the ruler can be removed with one hand.
 It provides added convenience, such as drawing lines with one hand.
