Our popular nf-90 (.90 mm thick: handmade range = .90-1.0 mm) is a classic 351 teardrop shape made from our proprietary "tortoise" casein material. As with all our products, it is precision machined, cut and finished, then hand tested in our 100% quality control department before leaving our facility. (PLEASE NOTE: We can't make these fast enough, as they are entirely handmade. Right now we have about a two-week lead time.)

We're sorry we're not faster. Our products are very much in demand, and we're fussy about quality. Generally, we ship within 3-5 days of the order being placed, then figure roughly another three days for the mail.
