The Mini Small Item Aid is a product from the www.activehands.com website, which has a huge range of aids for people with disabilities.
The soft, neoprene glove slides over the child’s hand and the velcro-on palm pad clamps any small diameter item firmly and securely. This two-part design enables the child to place the item they want to grip at any angle in their palm, to get the perfect position for play.
Hold pencils, crayons, toothbrushes, paintbrushes, drumsticks and more.
