Our warehouse is tremendous. Therefor it takes time to pick and pack each o-ring.
Given the low prices that we charge, we need to factor our warehouse time/cost in the order. We do not want to raise our prices and we don't want to add a surcharge to each possition. Therefor we decided that we prefer to give you more value for money by giving you more o-rings instead. We hope you understand and appreciate this.
