Thank you for your review, Windy Mesa. We're sorry to hear that you're not happy with the updated Unisub sheet. Unfortunately, Unisub can no longer get their previous hardboard base. They continue to work on finding the right base that is comparable to what they had previously. In the meantime, JPPlus has pulled all our sheets out of stock. Our customer service department will reach out to you shortly to see what we can do to help you out.
