This bag of 20 assorted blue detectable plasters is ideal for replenishing a catering first aid kit and come within their own resealable bag. They protect against cross contamination between blood and the products handled, whilst providing a visually detectable product due to its blue colour should the plaster become loose. All our blue detectable plasters are tested according to ISO 10993 and are hypoallergenic, non cytotoxic and latex free.
