Bottle Caps

[sanman969]

I have been buying bottles from Speciality Bottle (great service BTW). The standard caps come with a cardboard(?) insert in the top of the cap. I have noticed these inserts are starting to break down (stick to the bottle, discolor, delaminate). I have seen pictures of caps that have a plastic insert that tapers in a conical shape.

Anyone using these types of caps?
Are they better/last longer?
Any recommended supplier?

Yea, I've been using the 60 ml polycone amber bottles. I'd guess that they'd have to last longer than the cardboard insert caps, but honestly I can't say definitively because I've never used them.

I got mine from Wizard Labs. They have the 30 and 60 ml size. If you need a larger size, I can't offer any suggestions.

Good luck!

They are all over Amazon, just search "boston round" and you find them in 1/2 oz up to 4 oz.

Good tip on the 'boston round' search phrase.

Also, if you need some bigger sizes, US Plastic Corp has them with the polycone caps up to 32 ounces:

I've heard good things about US Plastic, a lot of people here order from them.
