Yes. CNT film is die-cut to any 2D profile, and electrodes are routed to your outline — no tooling cost for most shapes.
Wearable builds use detachable controllers and sealed film, allowing hand or machine wash of the fabric assembly.
Dual protection: NTC closed-loop regulation plus an independent hardware cut-off, with an auto shut-off timer.
Full private label: logo, manual, colorbox, barcode and FBA-compliant cartons prepared to your brand guidelines.
Functional samples ship in 7–10 days; sample fees are credited back against your first bulk order.
