I recommend the store. Item arrived to my country (Turkey) in one week; the seller shipped it very quickly and the item came by air shipment. However, item stayed at Turkey's customs more than 1 month and today I took broken items. I think, someone at working customs intentionally broke them. An edge of the package seems to have squashed. Morever, inner product package was torn when it was opened by someone.

Order made on march 31, received on april 20 Balashikha mosk. obl. About the quality of the package i can not say anything. The son opened the package until i was there. All the wooden plates were intact, made qualitatively. The instruction is understandable. The son (8 years old) collected in 2 days. I only helped in a few places. The child is delighted. In some places used glue for strength. The only negative-there is not enough lock nut on the handle, it is always untwisted. I recommend. In case i will buy other designers from this series. I did not communicate with the store.
