After opening, I put it in a file and stored it in a dark place without assembling or taking it out. Immediate purchase is OK. I have multiple of the same product for sale. If you would like to purchase multiple items, please leave a comment, and I will create a dedicated page and offer a small discount. Please feel free to ask any questions in the comments.
