28mm Flange Kit

They’re fine but online it says they come with the bubble Silicone inserts but they only come with plain silicone inserts, not the bubble ones. Customer service is pretty good but they told me they don’t come with them so I had to show them the pictures from their website. Then when they did agree to send me some the only sent 1 and it was the wrong size. Waiting for an update but I’ve been happy with everything else I’ve ordered from them.
