Our boxes are sealed shut with plain brown packing tape. If you receive a package that looks like it has been opened and resealed with clear packing tape, this means your order has been tampered with while in possession of UPS or USPS. If you like, you can refuse delivery from UPS and then contact us for refund or exchange. You may accept the package as it might be fine, but if not, we can still help you, but please understand that problems with that order are probably the fault of UPS or USPS and not us. (This rule may not apply to items with a product number that starts with “CNV” as those are shipped from different locations that may or may not use brown packing tape)
