Glass Marbles, 18mm, set of 60

The set has 60 glass marbles.

The marbles come in six colors, ten of each: red, blue, black, green, yellow and white.

Each marble measures 0.75-inch (18 mm) across. A drawstring pouch holds the set.

Objects primarily manipulated through touch provide tactile stimulation, and tactile stimulation contributes to both sensory perception and affective experience (McGlone et al., 2014).

Details

• Set: 60 glass marbles (ten of each color)

Pairing Note

Textiles: Kinetic tools paired with textiles become structured tactile regulation. People combine hand movement with textured objects because predictable resistance and smooth surfaces stabilize the nervous system and reduce physiological arousal within 60-90 seconds (McGlone et al., 2014). These practices persist because tactile-movement pairing lowers stress hormones (McEwen, 2007) and supports emotional grounding (Panksepp, 1998).

Visual: Kinetic tools paired with visual items become guided fine-motor pacing. Communities use visual cues to shape hand movement because simple visual anchors reduce cognitive load (Sweller, 1988) and help maintain steady rhythm during repetitive tasks (Nakamura & Csikszentmihalyi, 2002). This pairing endures because visual-motor integration improves coordination and supports calm focus.

Sound and mind: Kinetic tools paired with sound and mind objects become rhythmic regulation. Groups use quiet auditory cues, soft clicks, subtle shifts, or near-silent mechanical feedback, because rhythm organizes motor output and supports emotional stability (Clayton, 2012). This pairing persists because rhythmic movement increases endorphins (Harvey, 2015) and strengthens social and internal coherence (Dunbar, 2010).

Aroma: Kinetic tools paired with aroma become environmental grounding. People use aroma in regulation spaces because aroma shapes limbic interpretation (Herz, 2016), reduces vigilance (McEwen, 2007), and supports emotional clarity (Panksepp, 1998). When paired with fine-motor movement, aroma helps define safe space and deepen sensory calm.

Kinetic: Kinetic tools paired with body care products become mechanical surface regulation. Individuals combine oils or balms with hand movement because glide and pressure influence comfort and tissue response (McGlone et al., 2014). This pairing persists because mechanical-surface interaction reduces inflammation (Tracey, 2002), supports recovery (Kjaer, 2004), and reinforces personal grounding practices.
