A compact, ultra-strong neodymium countersunk pot magnet built inside a plated-steel case — perfect for hands-on maker play, classroom STEM experiments, and crafty display projects. The steel casing boosts the magnet’s holding power, while the countersunk hole lets you secure the magnet with a matching screw so it mounts flush and stays put. Use it for building magnetic displays, holding parts during craft builds, simple fixtures, or small mechanical projects that need reliable grip. Designed for hobbyists and DIY learners who enjoy experimenting with magnets and construction-style play; exact age recommendation not specified on the product page — use with appropriate supervision for younger children and keep away from small-child hazards.
