Storing wooden toys in the loft question

[hippospot]

I have some wooden toys my DCs have outgrown and I'd like to keep them for the future (grandchildren). I plan to store them in plastic lidded boxes. Do I need to use silica or other dessicant sachets to prevent mould? If so, where would I buy this type of thing?

Thanks

Sorry don’t have an answer but wonder if those vacuum bags would work for this??
