These genuine Texas parts came to us as part of a lot of surplus stock from a large (Milspec) type Co. they are as new and are stored with us still in their original tubes and outer packaging, however as they have been kept in storage for some years we have classified them as ‘new other’.

You will receive a cut length of tube containing the quantity ordered in ‘AS NEW’ condition, see photographs, they were taken of the actual chips for sale – authentic Texas logo and markings, beware listings that just display a generic chip!
