Update per late 2021.
In these current circumstances shipping is in a very complicated situation. Postal services in the Netherlands still works as before the crisis only at a very slower rate.
To be sure of arrival and possible 'return to sender' scenario's all orders outside of Europe are tracked by default. Orders outside of NL shipped without tracking are at the risk of the customer.
Please keep this in mind when ordering: Post is very much delayed by default.
Regularly post inside of the Netherlands should take no more than 3 days, the minimum is now 3 days and it could take 2 weeks, sadly.
Post outside of NL is slowed down as well and I can only guess by how much weeks it's slowed down. A good general rule of thumb is to add 2 weeks to your regular shipping times.
