This is a dial-type analog timer! It's a mechanical timer, so no batteries are needed, and it's easy to use. Perfect for managing children's smartphone or YouTube game time, or as a kitchen timer! The maximum set time is 60 minutes, and a bell rings for about 5 seconds when the set time is reached, notifying you with sound. The remaining time is displayed with color coding, so you can see the remaining time at a glance. Also, the numbers on the dial are large and very easy to read. It has a magnet, so you can stick it on the refrigerator, etc. You can use it for cooking, studying, work, and as an educational clock for children to learn about time, numbers, concentration, motor skills, and dexterity. 【Size】 Diameter 6cm x Thickness 3.7cm 【Materials】 Stainless steel, ABS plastic, magnet ■Shipping Method: Japan Post ※Delivered as mail and placed in the mailbox (items that don't fit in the mailbox will be delivered). ※If it doesn't fit in the mailbox, a delivery notice will be left. ※Delivered in an envelope (simple packaging) or a宅配用ビニール袋 (delivery bag). ※We try to ship as soon as possible, but as I work, it may take 1-2 days.
