We stock various sizes and lengths of these Silver Pins which have certain advantages 

 over the entomological pins (whether enamelled black or silver or gilt). 



For instance, insects liable to become greasy and to verdigris like Sesiidne, etc., are 

 best pinned on Silver Pins which will last much longer than ordinary pins. 



We shall be pleased to send pattern cards on application.
