The barrel is on the heavy side, but I don't think it's too heavy and I'm normally someone who doesn't like heavy pens. The designer cover is absolutely gorgeous, but it's only a sticker, so it may peel off over time, I look on the bright side though, if that happens it just means I can swap it out for an updated pattern. The seam might be a little annoying if you're writing a lot though, it *is* quite pronounced.
That aside, I love the pen and recommend it to all Papyrophile (stationery lover).
The chart below outlines the inserts sizes we sell here at Planner Peace, with A4 used as a comparison. The planner cover will be a little larger than this. E.g. A5 inserts measure 148mm by 210mm and the A5 ring planners we sell measure 190mm by 250mm.
