I do love these vases, they are great for those who are visual organisers, who need to be able to see clearly how many pills they have before they need to go be a refill a script. They are also quite accessible in the fact that their lids are easy to open, so if you struggle with stuff like that, these are awesome.
The only thing I will deduct a star for is because I worry they might not be super durable. They are a beautiful fine glass vase, I could see these being very easy to knock over, shattering the glass and flinging pills everywhere.
I think if you sold a pill vase holder (think test tube rack), where these could be securely kept when not in use, and easy to slip out/pull up when needed. I would totally buy this if you sold these. I know this could greatly improve accessibility!
