I can’t believe that I’ve managed to run out of Blocks. I know I didn’t lose that many! Anyway, I ordered some more from Amazon. I have Prime so there were no Shipping charges. I bought a small pack of 30 Blocks directly from Model Shipways and they charged me $9.99 for Shipping for a pack of Blocks who’s Shipping Weight is negligible. Probably about the cost of a regular letter. Certainly no more than 1oz… As a matter of fact, I weighed them and they weigh 1/4 oz!!! So my advise is to order Blocks through Amazon to avoid the ridiculous Shipping Costs.
Anyway, the pack on the left are Single Cleaves and the one on the right are doubles.
