The Humidity Control Case has been developed to allow you to perform the best possible track repair work. With your cored wire arriving on the job in top condition. Made in the UK.
 
The case is made lightweight, but is strong enough to handle all the knocks and scrapes it is likely to come across. Moisture is absorbed from the sealed unit by the use of a rechargeable silica sack, that can be re-energised in a conventional microwave.
