I know there's different sizes and I've got hundreds of these Daisy screens only to have most of them pulverized glass mixed in. I've never bought less than a hundred at a time and I hope these aren't too small or too big being 100 count glass pipe screens is usually about 10 bucks. But to only get 30 I hope they're all intact and most importantly I hope they fit most 14.5 mm male joints and most glass pipes. I'll try to call somebody in the morning but please email me if this is the right order being it only takes two to three business days but you should add an extra day onto that from California to Florida. Just saying I lived in Arizona and it takes an extra day. Just hoping they're all intact and I hope they fit being there going to be a 30 count for the same price as 100 basically. Thank you for your time and understanding, Richard P Matthew Jr
