※ Please be aware that inferior copies of this product are being sold. This design was conceived by us and commercialized after extensive real-world testing. (It 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 release, with over 700 units sold and numerous repeat customers. We have never received a negative review. We highly recommend this product with confidence. Despite the reasonable price, it has an adhesive force of over 2kg. Imitation products have less than 1/3 of this force, so there is a risk of detachment 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. Including prototypes, we have been using it for over 2 years (over 34,000 km of driving) with magnetic attachment in the engine compartment and behind the fuel filler cap, and there have been no problems such as detachment or rust. We use strong magnets, providing sufficient adhesive force. Material: Polylactic acid resin Magnet: Neodymium magnet 【Size】 Outer dimensions: 59mm x 42mm x 11mm (thickness) (Thin design allows for attachment in tight spaces) Inner dimensions: Φ31.9 x 8.7mm (depth) Confirmed to fit Apple's Airtag and LNEE's findmy tag 【Installation Method】 2-WAY installation: Magnet and cable ties. 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 ・Due to production by a 3D modeling machine, there may be 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.
