I have these 5gm tubes of high quality silicone for sale. Their very handy to take alone on your next dive adventure. It’s the larger tube in the picture. The smaller tube is a tube of silicone that came with a major manufactures housing. I also put a AA battery in the picture for comparison.
Each tube is $ 2.00, buy several I have hundreds of them.
