Betterbee has some flip top lids, like you describe, featured in their catalogue, latest issue, for 0.07 cents each for 1 - 1799 count. 0.5 1/2 cents for plus 1800. " One of the best bargins in the industry ", or so they say.
The lids are 38 mm and fit a variety of bottles.
I would say that ALL of the bee supply companies offer pretty much ALL the same " stuff " concerning honey containers. I like the " skep " bottles and use the 16 oz size for selling. You can do a search for plastic containers and usually end up going to the Bee Supply companies for them. There are countless plastic containers available in the country.
I do a little comparison shopping and settle for the best price with no sales taxes and closest for lowest shipping cost.
Generally speaking you will pay around 0.50 cents each for 1 lb. plastic containers with lids, labels and shipping.
