I believe the silicone still has some flexibility, but it's likely quite old. Please purchase only if you understand this. I am not knowledgeable about this item, so please make your judgment based on the photos. (An elderly relative closed their diving shop, and I am clearing out the warehouse inventory.) ※ Shipping from Okinawa often takes about a week to arrive. Please refrain from purchasing if you need the item urgently. ※ I have a cat. I will clean the item thoroughly before shipping, but please refrain from purchasing if you are concerned. I do not smoke. ※ I will use recycled materials for packaging.
