I hope this message finds you well. I wanted to follow up on my previous inquiry regarding the product dimensions we discussed. Since I'm confident about the specific size I'm looking for, I would appreciate it if you could provide me with a size range. This would really help in determining whether it fits within our project parameters. Additionally, if you have any recommendations or variations for the size that you think would be suitable, please feel free to share them. Having a couple of options to choose from would be incredibly helpful as we finalize our decision on this order. Looking forward to your prompt response!
