Do you have all the PO-Bx series of inlaid monogram chips? Seen much less frequently than the reverse inlay PO-Ax and PO-Cx type.

Here are a pair of "L"'s to get your started... a lavender and a purple. You might think these are from a Lueders family set, but I found a quantity of them in a shop. Square-edge design.

Both for $3, delivered.
