odd looking glass collection Free 3D model

both .blend and .fbx contain 3 glasses that one of them is 4-sided , the second one is 5-sided and the third one is 6-sided I tried my best to uv unwrap them but since it's gonna be used with glass materials it doesn't really matter. details for each glass : (results are for after you apply the subdivision modifier for .blend file) (all the faces are quads) for 4-sided glass: vertex count: 1666 --- face count: 1664 for 5-sided glass: vertex count: 2082 --- face count: 2080 for 6-sided glass: vertex count: 2498 --- face count: 2496
