OMG GLUE N SEAL by Ranger is the BEST glue in the world for tiny hard to apply to dies. It comes in Glossy and Matte and the Matte is the one you want. The really good news is that they sell it at Michaels. You can use a coupon. The other really good news is that it is NOT expensive, It comes in two sizes. The small one has a built in brush. I get both sizes and refill the small one because I like not having to clean the brush. Here is a link for those of you who don't have a Michaels close. Also so you can see what you are looking for. This is the small Matte size. You can get it all over the project you are working on and you won't see it when it dries. It is AWESOME!!! It is definitly my go-to glue!!!
