I bought a bunch of patches from different PUL teams including the PUL logo patch. The smaller the patch the more difficult they were to iron on, so the PUL logo in particular didn't stick. It might be better if the item you're fixing it to is easily reversible and you can iron on from the glue side of the patch. Currently considering my other glue options... Otherwise they are nice quality.
My order came quickly. The questions I had about this and other items have been answered very efficiently. Truly a great team works for this company!
