Yes, they're on backorder at Lencarta, sorry about that.
Quite a few items are out of stock or low stock at the moment, but I should have a delivery date for everything very soon now.
The bad news is that Lencarta is a victim of its own success, and the rapid growth in sales has led to shortages of some items simply because it takes time to make batches and get them into stock.
The good news is that there will be a lot of brand new products, way better than anything available from other people, in the next major delivery.
