Thanks Roger, for explaining how you have been storing your figures.
Actually, I have never had my whole collection on display. I've only ever had 10% out at a time, but that's only been the last few years. For over 20 years I've had my collection in complete darkness. And in Australia it was never on display. Always stored.
For a very long time it's been stored in trunks - the old carriage style with hessian coats and the wooden bands around them. I'd keep them in card boxes, and also some even in metal tins. And I'd wrap most figures in kitchen roll from 20yrs ago. And just normal tissue paper. They have travelled by sea from Australia to Scotland a couple times, and even in the crazy Australian humidity and very high temperatures, every figure has been 'perfect'.
I've never used acid free paper.
I will protect the spaces in between antlers and horns with thin strips of bunched up little balls of kitchen roll, and even cotton wool balls, and then wrapped the whole figure in a strip of kitchen towel.
The animals that didn't need this extra protection just got lined up side by side in their herds. And then I'd put a sheet of paper or card and layer the next lot on top until the box was filled.
I've never stored any figures in a sealed plastic bag. It's always been a cardboard box, usually those decorated types, or the blank ones that you can decorate yourself - either the type you buy in home deco stores like Ikea or B&M etc. Like shoe boxes anyway. And I've used fancy and beautiful card boxes from porcelain ornaments and Swarovski crystal items to store them too, and also ones from home appliances like kettles
I have a few tiny figures in little plastic boxes - around cigarette box size or a bit larger that are over 20 years old. I put the rabbits and hens and piglets and lambs in them, on a base of tissue. And then they are put inside their herds in a large card box.
But I've not got any large figures stored in a plastic box per se.
I will take some pics sometime to show you.
I currently have my Starlux figures in kitchen towel in card boxes. They are all swaddled up in separate cocoons to keep them well protected.
I have had Starlux stored this way for around 15 odd years. I remember buying my first Starlux models around the turn of this century and being amused by their quaint and beautiful appearance and strange yet brittle looking bodys. So I wrapped them well. And they are all in perfect health, - when I rediscovered them last year in a box by surprise!
I'm an expert packer and spent the majority of my life moving, so protecting my collection was a priority, both in storage and travelling.
Incidentally, like you Roger, every model I have has had a good scrub and wash in a tub of soapy water and rinsed thoroughly and air dried.
My trunks have never been in a hot environment in Scotland, always stored in a cold/cool room.
I have a little bag full of these sticky models you mentioned. Most of them came as extras from purchases and not from my own collection. They've all been thru my rigorous decontamination process, but still had that tacky feel. I've always kept them separated from the herds.
I will take some pics to show you the variety and label their conditions. I find it curious too.
The thing the majority of them have in common is that they have a heavy type plastic/rubber feel to them that has become tacky and feels quite yucky
And there are an assortment of brands.
