What's included

These are delivered in a sealed ESD bag, with pinheaders included.

I'm merely reselling these AS-IS to make it a one-stop-shop for building your keyboard.

Please note! You can likely find them cheaper on AliExpress or similar if you are willing to order from various sources. I'm merely covering my expenses, shipping/taxes etc, with no actual profit on these.

Normal handling time is 3 - 5 working days, not including build items (Those usually take 1 - 2 weeks).

Shipping is done with insured/signed for parcels, where no such service is available the parcel is sent as insured parcel, but may not be fully traceable the entire transit. If no insured or traceable service is available, parcels will be sent as uninsured/untraceable at the buyers responsibility. All of which is clearly stated on checkout.

All packets are represented to courier services and customs at their true sale value, and all responsibility for import fees, taxes and tariffs lie with the buyer.

The SE/EU "Act on Distance Contracts and Off-Premises Contracts (SFS 2005:59)" allows returns of the items in undamaged (unsoldered!) condition within 14 days of receiving it. Return shipping on returned items are the responsibility of the buyer.
