Hi Stacy
Welcome from the Scottish Highlands!
Maybe you have spent a lot on the Playmobil, but you can always tell your husband it is an investment.
Other toys will break easily and lose their value - your kids will play with their Playmobil for many years to come. If they eventually do lose interest, you can keep it for your grandchildren to play with. Or (if it is looked after well) you can get your money back by selling it.
There are a few topics around here on storage. The easiest way to find them is by putting relevant keywords in the search bar.
Have fun at
