Hotz Mats have announced that they will be releasing three new mat designs in June.
From their website:
We have been working on three product releases and these should be released in June. One of the new products was actually completed in July 2010, but because of the complexity of the product, we needed to set up additional equipment. Hopefully, this will be completed before the end of this month. Our new print screens should be in our studio by Friday after which we will conduct tests to ensure they are working properly (last month one of our new print screens had to be sent back due to an error; this caused us a two week delay too production of the product).
