※ Please be aware that inferior copies of this product are being sold. This shape was conceived by us and commercialized after extensive real-world testing. (This infringes on the Unfair Competition Prevention Act (imitation of product form), and although we attempted to protest to the other party, we were already blocked. LOL) We are considering legal action. We have been manufacturing and selling cases since the early stages of AirTag's release, with a sales record of over 700 units and many repeat customers, and we have never received a negative review. We highly recommend this product with confidence. Despite being reasonably priced, it has an adhesive force of over 2kg. Imitation products have less than 1/3 of this force, so there is a risk of falling off due to vibration. Please be careful not to purchase them by mistake. This case is for fixing to cars, motorcycles, bicycles, construction machinery, agricultural machinery, etc. It uses a screw-type design, and securely holds Apple's AirTag or LNEE's findmy tag without any rattling. There is no worry about the lid coming off. According to a trick learned from a buyer, it seems possible to silence (reduce the sound of) the Airtag. We created this for tracking our own vehicles in case of theft, and for over 2 years (over 34,000 km of driving), including prototypes, we have attached it with magnets in the engine room and behind the fuel filler cap, and there have been no problems such as detachment or rust. We use strong magnets and have sufficient adhesive force. Material: Polylactic acid resin Magnet: Neodymium magnet 【Size】 Outer dimensions: 59mm x 42mm x 11mm thick (Thin design allows for attachment in narrow spaces) Inner dimensions: Φ31.9 x 8.7mm deep Confirmed to fit Apple's Airtag and LNEE's findmy tag 【Installation method】 2-WAY installation: Magnet and cable tie. Can be installed in various locations. 【Regarding magnets】 Reliable rust-proof treatment (3-layer plating) Very strong, so you can use it with confidence on the exterior of your vehicle (flat surface installation, on-road driving) 【Quantity discount】 From the second unit onwards, we will create a dedicated listing for an additional +600 yen per unit. ※Caution ・Made by a 3D modeling machine, so there are layer lines. ・It will soften slightly around 60°C. ・When attaching the magnet, avoid curved surfaces and attach it to a flat surface. ・AirTag has an anti-stalking function. Please do not use it for purposes other than the correct ones. ・AirTag is not GPS. We kindly request that you refrain from purchasing for investigation, imitation, or theft of ideas.
