Getting into jewelry making? You'll need these! This is a handy set of 40 crimp beads from Beebeecraft. They're made from 304 stainless steel, which is great because it's tough, resists rust, and won't tarnish easily, even if it gets wet. The set includes beads in two sizes (though the title says 4, the description lists 2): small ones measuring about 3.5x3x2.5mm with a 0.7mm hole, and larger ones at 4x3x2.5mm with a 1mm hole. They come in a little plastic storage box to keep them organized. How do you use them? Simple: you thread your cord or wire through the bead, then use pliers or tweezers to squeeze the bead flat, securing the end of your string and preventing beads from falling off. Essential for finishing necklaces, bracelets, anklets, and keychains. A must-have for any DIY jewelry toolkit!
