BULK SET OF 144 BALLS (12 DOZEN). Kids love these little soft and squishy hedge spike balls. They are 1", and come in 5 colors. These balls are fun with tweezers or tongs for fine motor play, sorting, or using for practicing using pincer and thumb opposition in occupational therapy. They can also be used in pencil position training. Keep a ball or 2 clenched in your 2 extra fingers and palm while you hold your pencil properly with the thumb and other 2. These are also fun finger fidgets because they are squishy, and you can squeeze a few in your hand and roll them around to keep your hands busy. These popular toys make great birthday goodie bag fillers or popular treasure box prizes or classroom rewards. Fidgets are a self-regulation tool used with children who have a difficult time sitting still or focusing. Fidgets help promote focus and concentration, and keep the body (fingers) busy so they can still sit and focus! Fidget toys are also great for strengthening hand muscles and building fine motor and finger dexterity.
