Please store unpacked material wrapped in aluminium foil, in tins or plastic bags (PE / PP). Please avoid unhardened FIMO coming into contact with polystyrene (PS), PVC or Styrofoam, since the surface may undergo a chemical change – as described in your mail.

7 weeks after I posted the initial 3-day test, things are now as follows:

- The Kato still shows no reaction with the container at all. The clay is just as it was, and there are no marks or residue visible on the container.

- The Premo has now left a definite frosted-looking mark on the container where it's been sitting. It's not stuck, and the consistency of the clay still seems pretty normal, but there's definitely a reaction.

- And the Fimo has basically become part of the container. Yuck!

I have also had problems with putting 2 pieces of Fimo cane in a plastic bag together and them sticking to each other – pulling parts off when I tried to separate them. I guess I should get some UK Glad Wrap equivalent to avoid that in future and probably use a blade to separate them instead of just pulling – would have cuased less damage.

@Jocelyn: I have a bunch of canes that I have now put into a plastic drawer unit a friend gave me. It is compatible with the clay and since the drawers are covered I don't have to wrap these canes either. It is easier if you don't have to go to the effort, plus they are easier tot see that way.

They're a nice height for working at while standing, but I also got a stool ("Julius", 63cm version) in case I want to sit and work.

You can add shelving, cabinets and drawers underneath, but my local IKEA was out of stock over the Christmas break… when they are back in stock I'm adding one set of open shelving, two sets of drawers, and one cabinet which I'll line with sound absorbent foam to make a "home" for my neat but noisy vibratory tumbler.

The container base and dividers are exactly the same type of plastic (SAN plastic according to IKEA's web site, i.e. styrene-acrylonitrile resin), and that same plastic is also used for most of the lid (the big see-through panel).

The lid uses a second type of plastic (ABS plastic, i.e. acrylonitrile butadiene styrene) for the outside edge of the lid and its clips, with synthetic rubber underneath where the lid sits on the container base.

I'm really happy with them. They fit my bookcases perfectly both vertically and horizontally, they look good, the lid clip mechanism is very practical, and the fact that the lids are mainly completely clear too means light penetrates the stacks of boxes well and all the colour and detail inside is perfectly visible while everything is still sitting on the shelving.

I bought my local IKEA out of them, actually ("you AGAIN???")… and when they restock I'll be back for some more!

@Jocelyn: That's great to hear that you're getting more and more set up. It is fun planning spaces to do crafts in, isn't it! I just the love the 'potential' in it all.
