the blocks are made of maple, give them to someone with a fireplace or firepit for starters.
the clamshells...wow I use them for everything. I like the fact the you can see through them. The medium size fit A2 cards perfectly...great for a gift of cards for someone, just wrap with ribbon.
They also protect items that you may be transporting for a class.
In the med. case I put together an adhesive "kit" that includes glue dots, tombow, smaller rolls of red line tap, dimensionals...etc. That way I always have the proper adhesive for card clubs or stamp a stacks.
