Using your Palm Tangle Metallic is super easy. Just hold it in your hand and start twisting, bending, and turning the sections. You can use it while sitting at your desk, watching TV, or even when you're feeling a bit anxious. It's great for improving the movement of your fingers and wrists. When it comes to maintenance, you can simply wipe it with a dry cloth to keep it clean. As for safety, always keep it away from children under 3 years old because the separating sections can be a choking hazard. And if you want a variety of colors, order the pack of assorted colors. If you need a large quantity, go for the box which contains a full case of Tangles.
