You don't want the ones with spikes, BTW.They're scratchy and can damage the garment, other garments, and you. Practice with these.They do require the "perfect amount of smash" to install properly. Edited to add: I really like this set from the Digital River O'Merch.this one is good too, slightly cheaper, different tools and colors to play with. Sometimes it's finding the tool that works best with your style of application.
