If you do not book a tour in advance (and you can only book it in advance, which you learned during the visit), then it is not very interesting. We walked around the hall, read the information. Real (antique or modern ) there are no belts, only photo prints. You can see a modern machine, but without a guide it is not clear what works there and how. So book the tour in advance
. P.S. the only real belt in the museum is a bookmark for books in a souvenir shop for 95 rubles.
We travel a lot around Belarus. As a historian by education, I considered it my duty to visit this museum. We paid for the tickets after searching for an employee, came to the halls and were incredibly disappointed. There are a lot of copies of belts, the exposure is very small and weak. It was interesting to look at the modern machine. In general, 20 minutes is more than enough for a visit, but I definitely won't recommend it. It's much more interesting in local lore.
we arrived from Minsk, decided to visit the museum, but we were not allowed, because at that time there was an excursion (of 2 people), and we could have overheard something. the rude "auntie" did not behave professionally, raising her voice insisted on buying a more expensive ticket and going on an excursion. we explained that we wanted to walk around the museum, see the belts and the tradition (going to the museum is officially allowed :)). we were unpleasantly surprised by the whole situation.
and at the end of September we visited the Narodova Museum in Warsaw, where we saw the native Slutsk belts.
