I purchased a full Seebeck Peltier set this year, but it was too cold for my work (this is a personal feeling), so I only wore it once. I purchased a 50000mAh battery and joint wires separately, and it comes with one genuine Seebeck battery and 6 Peltier elements. The size is L, with a chest size of 94-102cm and a height of 170-180cm. Regarding precision instruments, <Notes> * I have checked it roughly for the purpose of listing it, but there is a possibility of unexpected damage or deterioration. Please check the images carefully before bidding. Therefore, bidding is limited to those who understand and agree to the above possibilities. After winning the bid, No claims and no returns are accepted. I will return the same evaluation for any reason.
