Hello dear friend, thank you very much for participating in our challenge, wow, what a good publication you present to us today, I congratulate you for this great work. The oxygen cylinder is something very important in the medical area.

Very good step by step, I think you were very creative, and your reason was very important, during covid many people died from lack of oxygen, so thank you for that reflection.

I hope you have a great day, much success in the challenge, greetings!😁🌷
