A: Hi Julia, I'm sorry that you are having problems adding the knit blockers to your cart. We have these in stock so they should add to your cart. Please be sure to check mark
the box just above the add to cart button that says Choose Options, I understand that: This item ships within the USA only. No International shipping available, sorry about that. Without checking this box the blockers will not add to your shopping cart. If you have any more problems please let us know. Thank you for asking. Tracy, Handsome Fibers.
