Standard spaying bottles are made of rubber and have a smell unique to rubber. Since this product is made of silicone, it has no odor, it can be used safely without corrosion even with menthol type. I think that it is good if you can sell things using silicone dropper rubber even with standard spike bottle.
Although I could still use the bottle, I thought that I had to replace the bottle because the Spyid became so irritated, I found this product in a monotalou. I was worried about the size, but it seems quite flexible, so I bought two kinds of bottles of different sizes. Thanks to that, it was saved and ecologically. Thank you very much.
