|Pilot Coleto 4in1 pen|
The top of the pen pops open and you slide the refills into place and then close the lid, easy-peasy! I ordered pink, purple, orange and green ones.
I found 3in1 barrels and 4in1's but they also come in bigger sizes to hold more colours. This 4in1 fits easily into the elasticated loop on my Apex Filofax but it does not fit into the loop on my Chameleon. It is not the end of the world though! I have really enjoyed using it to fill in the last few days of my diary for this week which I will show you tomorrow.
