What is the star system?
The star system calculates the number of pieces that were handled by Conchology, Inc. in the last 21 years:
| 0 – 5 pieces | 6 stars |
|
| 6 – 10 pieces | 5 stars |
|
| 11 - 25 pieces | 4 stars | |
| 26 - 75 pieces | 3 stars | |
| 76 - 150 pieces | 2 stars | |
| > 150 pieces | 1 star | |
We want to point out that the star system is only very reliable for PHILIPPINE shells only, as we handle very few foreign shells in general. As time goes, the system will become more and more performant.
