For Adults Kids with Autism: Providing a unique sensory stimulation experience, its spiky design can meet their needs for exploring different tactile sensations, help attract attention, reduce self stimulating behavior, guide them to focus on toys, and alleviate emotional fluctuations and anxiety caused by autism to some extent. As a daily item that can be carried at any time, such as in the form of a Spiky Grippie Stim Keychain, it is convenient for autistic patients to use in various scenarios such as going out, going to school, and seeking medical treatment, providing them with familiar and continuous sensory comfort and helping them better adapt to the external environment. For anxious individuals: Whether adults or children feel anxious (Anxiety Relief), by playing with this toy, the process of touching the spikes with fingertips can shift attention, divert the brain from the source of anxiety, and gradually relax the tense nerves. The slight "pain" (Pain Stim, Little Ouchie) of spikes can actually give people a novel and authentic tactile feedback, breaking the thinking patterns under anxiety and having a soothing effect on emotions.
