🇪🇺 EU Shipping Update

Due to exceptionally high demand, we have temporarily paused orders from new EU customers.

To ensure we continue providing the level of service our existing customers expect, EU ordering is currently available by invitation to returning customers only.

If you've ordered from us before, simply email support@ptlabs.shop and we'll be happy to help you place your next order.

We appreciate your continued support and look forward to welcoming new EU customers again in the future when capacity allows.
