ARK's Arrowhead Chew Necklace - Thin, Discreet Oral Sensory Support

ARK's Arrowhead Chew Necklace is a slim, wearable oral sensory tool made by ARK Therapeutic from FDA-compliant, medical-grade elastomer. Designed for children aged 3 and upwards and adults, it provides a safe and discreet outlet for the need to chew, helping to support self-regulation, focus, and calm. The pendant is free from BPA, latex, lead, phthalates, and PVC, and is manufactured in Columbia, South Carolina, USA.

How It Helps

What makes the Arrowhead stand apart from other ARK chew pendants is its slim profile. At approximately 5.7cm tall, 4cm wide, and just 0.75cm thick, it is one of the thinnest options in the ARK range - making it a natural choice for individuals who tend to chew on thinner objects such as fingernails, pen lids, pencils, or shirt collars. Its pointed shape also makes it particularly effective for front-teeth chewing. The arrowhead design has a stylish, understated appearance that suits older children, teenagers, and adults who want something that does not look overtly therapeutic or childish.

The necklace comes on a 76cm (30 inch) adjustable breakaway cord that releases safely under pressure and can be shortened to suit the wearer. It is available in three colour-coded toughness levels - Standard (softest, for mild chewers), XT Medium Firm (for moderate chewers), and XXT Very Firm (for avid chewers) - and in a range of muted, understated colours including greys, dark blues, and greens, reinforcing its appeal as a discreet everyday tool. It can be cleaned by handwashing or on the top rack of a dishwasher.

Why It Works Well in Schools and Classrooms

• Discreet enough for secondary school: the slim profile and muted colour range - including black, dark grey, teal, and forest green - mean the Arrowhead sits comfortably as everyday jewellery, making it particularly well suited to older pupils and teenagers who might resist more obviously therapeutic or brightly coloured chew tools.
• Targeted nail biting and pencil chewing support: the Arrowhead's thin profile closely mimics the experience of chewing on fingernails or pen lids, making it one of the most effective redirecting tools for these specific habits.
• Minimal disruption to learning: worn as a necklace throughout the school day, it provides continuous access to sensory input without drawing attention or interrupting lessons.
• Three toughness levels for individual matching: staff can match the necklace to each pupil's oral sensory needs, supporting tailored provision within EHCP and SEN intervention plans.
• Safety-tested and dishwasher safe: medical-grade materials and easy cleaning make it practical for schools and settings recommending or supplying sensory tools.

For Home Use

Parents and carers will find the Arrowhead Chew Necklace a reliable everyday tool for use at home, during travel, and in social settings. Its understated design means it can be worn confidently in any environment, and it is particularly valued by families supporting teenagers and adults with sensory needs who want a chew tool that fits naturally into daily life.

The Evidence Behind Sensory Chew Tools

Oral sensory-seeking, including nail biting, chewing on clothing, and chewing on objects, is a recognised behaviour in individuals with autism, ADHD, sensory processing disorder, or anxiety. Providing a safe, dedicated chewing outlet supports proprioceptive regulation, which can help reduce stress, improve focus, and calm the nervous system. ARK Therapeutic has been designing clinical sensory tools for over 25 years, combining the expertise of a speech-language pathologist and a mechanical engineer.
