This is one brand I really like. The Fiorentina notebooks I have are refillable and very reasonably priced. The leather is very hardwearing. The refills have thick cream lined paper with beautiful gilt edges.
They have many designs and models but the ones I like are these. First are some photographs of mine (the Three Graces) and then some stock photos showing the breadth of the range.
Mine come from Barnes and Nobel but they are also easily available on Amazon and large stationery retailers.
This one is not refillable but isn’t it gorgeous?
