These T-Shirt Ruler Guide - 4 Pack -Tshirt Ruler Guide Tool Sublimation Designs for Making Fashion Center Design, Adult Youth Toddler Infant are exactly what I needed. They are really nice quality T shirt alignment tool. This is great if you use a heat press and need to make sure your prints are aligned up properly. This is nice high grade PVC plastic that is easy to read. You get all 4 measurement guides that cover you from infant to adult. So far they are working out great and they help to keep your shirt measurements and placements in order when printing. Great quality and quantity for the price. Overall great buy and I highly recommend.
