Yes, me.
Historic Scotland had a wide range of them that could be sent out to schools, but were usually originally used for specific projects first. They had three made for an activity that Monarch and I travelled with throughout the Highlands and inner hebrides.
Bronze and Iron age, and absolutely lovely stuff.
Ehm, not quite sure what kind of information you're looking for on this.
The commissioned pieces ranged from re-created bronze age jewellery, weapons and axes to flints and woodwork.
It was all expensive to re-create authentically enough to be 'real', iimmc. That, and the fact that it was very tactile, very much stuff everyone wanted to handle, made it a pain to keep an eye on, especially with all the rest of the stuff. We were fortunate and didn't lose anything, but some pieces ...flints, and a jet necklace, were broken. It happens, and I repaired the necklace and we had another flint knapped, but if one of the bronze axe heads had gone missing then that was a couple of hundred pounds to replace.
So, think on your budget, and think about breakages/loses/perhaps replacement insurance of some kind.
The flints were authentically sharp, too sharp for children to handle without oversight and care....they were 'real' but the handling ones didn't need to be. I did carve up a joint of meat, and a chicken when showing them in use, but blunt ones would have been fine for the tactile bit....that's just an example, Victorian needles, or horn or leatherworkers tools are another sort of thing to consider, "Do they need to be sharp?", because there's always a numpty who'll try it; we barely stopped on rambunctious child from deheading another with a gladius on another event, and that was blunt, but it was still a heavy lump of metal being swung at another child by a strapping great lout of a what was technically a p7 child.
Clothing is always popular, but well, snot, sweat, occasional lice, bare feet and plantar warts.....and you have to store it.....I know why schools are often iffy about dress up boxes. You can end up with so many rules about using stuff that it kind of takes away the fun of the box if you're not careful.
Basically the box is best 'presented' by someone who knows about the pieces and doesn't let it become a rummage. Boxes sent to schools can be sent with all the instructions you like, but teachers get busy, and not every child/teacher/school is careful. If you price them out of the range of activities then they simply won't apply for them.
It's a balance between getting the stuff out there, it's costs, and replacement costs, and it's relevance to the curriculum or museum in question.
I don't think there is any definitive one size/style fits all. I think each situation needs it's own plan.
I'll see if I can find images, Tengu, but they were on the old site.
