310 Whistle Tip Carts - Where to Buy?

[bassnut]

Early on I bought some pre-filled whistle tip carts from Ijoye (5 pack) who's stock of many items is now gone. Got 'em cheap too. They came in a light blue and white box labeled "Mini Cigarette atomized cartridges" with no manufacturer info. Are these the mini DSE901 tips? They do fit the 510 atty.
These were the ultra flat tips. The whistle tips I see available now everywhere else are thicker.

I'd like to get some more. Who's got the ultra thinnies? What other tips fit the 510?

The 901s fit on the 510. That's all I use on mine.

If they're shaped like a D where the filler goes, they're 901 tips. A lot of places have them. I got mine from Litecig.
