It is a paper cup that is fully biodegradable. In its production, we use paper coated with a safe for people and the environment water-based barrier instead of PLA, so according to a common understanding of the SUP directive, you do not have to use the “plastic in product” logo, but to be sure, check your latest national regulations.

High thermal insulation (TW)

A Thermal Double Wall (TW) is a paper cup in which, between two layers of paper, we use a special hollow containing air, which insulates the hand from the heat of the beverage. By using this technology, this cup best insulates heat from all types of our products, making it best suited for take-away hot drinks like coffee to go.

The above-provided delivery times are valid for courier service only (for example, GLS courier parcels). Please read all the remarks below. Please also take into consideration that we cannot start production until the graphic design is finished (on the rainbowcups design template), checked and accepted, so the delivery time is also depending on you.

Delivery time

Delivery time is counted from the moment of acceptance of graphic design on the rainbowcups template and incoming of the prepayment (both conditions have to be fulfilled).

Delivery time will be additionally prolonged by all the holidays or days free of work that occur in the meantime.

If you want us to deliver to Great Britain, Switzerland, Norway, northern Sweden, Finland or any other remote areas or islands, it may take about 1 week more to deliver there on top of what we state. Prices apply only for the European continental part of countries, so do not expect us to deliver, for example, to Greenland, French Guiana or Canary Islands or any other islands using these…

We do not agree on Incoterm EXW (clients’ transport and pick up of goods from our warehouse).

If you want us to deliver by Euro pallet service

For quantities of goods of about one, two euro pallets or more, sometimes it might be cheaper or safer to deliver goods on euro pallets, especially to some main cities. It is not a general rule as for some products or destinations, the package service will always be cheaper, especially in the case of any remote areas.

Please remember that when choosing Euro pallet delivery, there is no bringing the parcel into the premises included nor the help of the driver with the unpacking. If you do not have a warehouse with a ramp, and you need a car with a lift – you need to stress this out.

If you want us to calculate the euro pallets shipment cost, don’t hesitate to get in touch with us and provide us with: the quantity of goods ordered, SKUs, destination country, postal code and city so that we can return to you with a quotation the next day. Delivery time might also slightly differ from the above.

Taxes and customs

Please check your company’s VAT number at VIES: http://ec.europa.eu/taxation_customs/vies/, if you are eligible for 0% VAT intra-Community supply of goods within the EU. For deliveries outside Poland but within the EU, VAT does not apply – it is 0%. If you do not have a valid EU VAT number, we must add 23% VAT to your order. For deliveries outside the EU, customers must pay all the additional taxes like VAT, and import customs (we deliver according to GLS “Incoterm 40 DAP, cleared”).

An additional fee applies per each order or shipment (not package) for customs clearance of every separate shipment to the UK, Norway, Switzerland, Serbia or anywhere else outside the EU. Due to customs clearance procedures, it is impossible to send goods directly to customers outside the EU in a no-name fashion (without our invoice inside). In courier service, we deliver according to GLS “Incoterm 40 DAP, cleared” delivery terms, so it means that usually, you also have to pay VAT and import customs if they apply in your home country. In the case of pallet service, depending on the provider, the delivery terms might differ. Customs clearance time, and therefore delivery time, also depends on your efficiency and cooperation with customs officials.


Rainbowcups is responsible for defects in products sold within 6 months of delivery (tested according to ISO 2859, AQL of 2,5 for leaking).
