Where shall i store the blocks in order to keep them usable? What is their durability?

I sotred the one I take to the gym in a plastic case like for sandwich works great, the others in a place where there is no humidity. The durability depends on the use, is a little bit fragile and craks little pieces but this is normal.

Is this chalk suitable for climbing?

I think you can use it as climbing chalk for indoor climbing or gymnastics. For outdoor rockfaces something more specific and much more expensive may be in order.

What size is this chalk? Is it a chalk Block?

Each small box contains a chalk block, the size of your palm. It breaks up easily, so once I put it in a sandwich bag and slightly squeezed it, it fell apart into small chunks.

Do the blocks come in resealable bags?

No, they come wrapped in a paper. I just put my block in a gallon Ziploc baggie so I have room to rub my hands in the bag without making a mess in the gym.
