I use mine with a self-adhesive magnetic foil to attach a piece of a paper or cardstock and keep it in place. They are very small, therefore thay can be removed easily. Review: Incredibly weak - Really weak. Bought them to magnetize and transport some miniatures that are a few grams a piece and it take around 5 magnets to get them even remotely sturdy. ## Features - Pack of 10 - 8mm diameter x 1mm thick - +/-0.1mm tolerance - Each magnet's north and south pole are on opposite curved sides - Excellent resistance to demagnetisation - Coated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth finish ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008UADQN0 | | Best Sellers Rank | 76,452 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 510 in Rare Earth Magnets | | Brand | FIRST4MAGNETS | | Colour | Silver | | Country Of Origin | China | | Customer Reviews | 3.8 out of 5 stars 69 Reviews | | Global Trade Identification Number | 05060185923629 | | Item Dimensions L x W x Thickness | 8L x 1W x 1Th millimetres | | Item Shape | Round | | Item Thickness | 1 Millimetres | | Item Type Name | 8mm dia x 1mm thick Diametrically Magnetised N42 Neodymium Magnet ( Pack of 10 ) | | Item thickness | 1 Millimetres | | Manufacturer | Magnet Expert® | | Manufacturer Part Number | F322DM-10 | | Material | Copper, Nickel | | Material Type | Copper,Nickel | | Model Number | F322DM-10 | | Number of Items | 10 | | Number of Pieces | 10 | | Product dimensions | 8L x 1W x 1Th millimetres | | Shape | Round | | Unit Count | 10.0 count | ## Product Details - **Brand:** FIRST4MAGNETS - **Colour:** Silver - **Material:** Copper,Nickel - **Product dimensions:** 8L x 1W x 1Th millimetres - **Shape:** Round ## Images ![Diametrically Magnetised N42 Neodymium Magnet for Reed Switches, Rack and Pinions, Shafts and to Provide Rotational movement - 8mm dia x 1mm thick - Pack of 10 - Image 1](https://m.media-amazon.com/images/I/41fmRv7U8PL.jpg) ![Diametrically Magnetised N42 Neodymium Magnet for Reed Switches, Rack and Pinions, Shafts and to Provide Rotational movement - 8mm dia x 1mm thick - Pack of 10 - Image 2](https://m.media-amazon.com/images/I/61hFQKhOgjL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very good quality magnets *by P***A on 11 January 2017* Very good quality magnets.
