The hazard: High-powered magnet hazard

This recall concerns small, strong magnets that can detach. Teenagers are at risk as well as toddlers, because magnets get used to mimic tongue and lip piercings.

What the notice says: The lithium-ion battery and electrical components in the recalled hand warmers can overheat and ignite, posing a risk of serious injury from fire and burn hazards.

Why it matters: Loose high-powered magnets are dangerous when more than one is swallowed. They attract each other through the walls of the intestine and pinch the tissue trapped between them, an injury that usually needs surgery.

Symptoms and when to call a doctor

If you think a child has swallowed magnets — even if they seem entirely well — go to an emergency department and say magnets are involved. Early symptoms are indistinguishable from a stomach bug: stomach pain, vomiting, poor appetite. A single magnet may pass on its own; two or more rarely do, and the team needs to know how many are unaccounted for.

Products covered by this recall

This recall involves Kobayashi's HotHands-branded rechargeable hand warmers. The white with orange hand warmers were sold in packs of two warmers that can be magnetically joined together and include a charging cable. The hand warmers have a USB-C port to charge the built-in lithium-ion batteries in each unit. The adjustable-heat hand warmers have LED indicator lights on the hard plastic shell and come with a silicone lanyard. Model number "H163650" and the batch number are on the hand warmer's underside, and the white HotHands logo is on the top and on the product packaging. Only electric rechargeable hand warmers with the white HotHands logo are included in this recall.

What to do about Magnets

Kobayashi — This recall concerns small, strong magnets that can detach. Teenagers are at risk as well as toddlers, because magnets get used to mimic tongue and lip piercings.

  1. Put the product out of reach and count the magnets against the number the instructions say it should have.
  2. Follow the remedy described on this page rather than keeping the item with the magnets glued back in.
  3. Check under furniture and along skirting boards — stray magnets travel further than you would expect.
  4. If any are unaccounted for and a child could have reached them, go to an emergency department and tell them magnets may have been swallowed.

How the remedy works

CPSC recalls specify one of three remedies, and which one you get is not negotiable — but how smoothly it goes often is.

  • A refund means the purchase price back, sometimes prorated by age for durable goods. Ask how they calculated it if the figure looks low.
  • A replacement is usually the current model, not the recalled one. Confirm the replacement is not itself under recall.
  • Several recalls now ask you to destroy the item and send a photo as proof. Register the claim before you do that, never after.
  • Return shipping is the company’s cost. If you are asked to pay it, push back.
