L LTGEMFingertip Pulse Oximeter Case, Portable Blood Oxygen Oximeter Storage Case (Case Only) - Black

That it fits and it's a nice case to protect it

The elastic strap inside is a bit snug, I just cut it out. The case itself is rugged, and seems very durable. I have to carry a pulse ox everywhere I go, and this is so much better than the Velcro bag that comes with them. Good semi solid case for protection.

Great

No oximeter arrived in black zippered case please send me one

I like this sturdy case. It protects my oximeter well. The exterior is hard and the inside is velvety soft. An elastic band holds the oximeter in place. My brand fits fine with a little space to spare. The case has a small area on the upper interior lid to hold items such as batteries (if it fits with your model) or a charging cord. I travel with my oximeter (esp. when going to high altitudes). This case will protect my device from shock during travel and keep it dust-free at home, too. I hope this information helps you.
