To give you a complete size range  this Midi Egg-it lies between the mini and standard Egg-it, with the same soft, silky feel and when wet slushy likened to cotton wool.   When fished it creates a halo effect on its outer edges.  In this size will be ideal for micro eggs, worms and mini lures. 
It is now becoming a favourite when fish turn finicky and anglers need to 'fine down' their fly sizes.  Approximately 3 metres per pkt.
