For those asking about the Naked Marshmallow Toasting kits, we got them last Christmas, 1 each for our 4dc aged (then) 7 through to 15.
Some flavours were better than others but they were a big hit and the burners still have fuel in. We probably get them out once a month for a pudding.
We have since gifted them to 16 and 8 yo dn’s and they too have been a massive hit. We were asked to get a 3rd dn their own kit on the back of it.
The marshmallows themselves I buy every so often if I get an offer and although they have a use by, we’ve never noticed them go off.
I promise I am nothingto do with Naked other than a satisfied customer (who may have also preordered the advent calenders 
)
