The snaps can be fastened to make it a coverall. Regarding shipping: Items will be simply packaged using recycled materials and shipped via the most affordable method. There is a possibility that we will ship via Yu-Packet Post instead of Nekopos without prior notice. Please let us know in advance if this is a problem. Other: We carefully inspect the items, but as amateurs, we may miss something. Also, there may be individual differences in the condition of the items. Please refrain from purchasing if you are concerned about minor details. Please feel free to comment if you have any questions. We will do our best to assist you. Thank you for reading to the end.
