Reusable hot/cold pack utilizing non-toxic medical grade clay in place of gel.
Heat in microwave, cool in freezer.
Pack has printed instructions regarding how long to heat/cool for.
Clay is more effective than traditional gel packs because it retains heat better and is very soft, meaning it does not 'flow' and so forms to the body without leaving 'empty spots'.
Remains flexible when frozen, even below minus 25 degrees celsius.
Supplied with soft, padded towelling bag with elastic/velcro strap for securing around body.
