In fact, it seems that such a simple design has been put on sale and was not intended to be uploaded. However, I just found out that it was copied by other families one by one ~ it is really a big difference. at least changing the internal logo is also a respect for the original.
This humble lid design is also refined from my more than a dozen lid designs, which have been selected and modified several times. The size ratio of the bottle body has also been selected and adjusted many times.
Very practical, the main light, easy to clean, soft ~
